    Interface studies and electrical properties of plasma sulfide layers on n-type InP (1988)

    Notizen: The growing conditions and the basic interface properties of InP-sulfide-metal structures formed by direct and indirect plasma-enhanced sulfidation were investigated. The grown-in sulfide layer is an admixture of InPS4 and In2S3. The relative concentration of the low-gap indium sulfide is responsible for the high leakage currents (10−3 A cm−2) in the direct plasma layers. In the indirect plasma case the leakage currents are reduced to 10−6 A cm−2 with breakdown voltages about 7×106 V cm−1. The current transport and the frequency dependence of the capacitance of these diodes are consistently attributed to traps located in the sulfide near the semiconductor (SC) surface with a concentration in the 1011 cm−2 range. Detailed measurements of the capacitance-voltage characteristics reveal that the Fermi level in InP is swept through the upper half portion of the band gap and that accumulation and strong depletion regimes are reached. These measurements also reveal that the room-temperature hysteresis-free C-V plots result from the compensative effects of mobile charges in the sulfide and of charges trapped on the interface states. Separation is made by freezing the mobile charges either in the nearby InP or Au electrode region and the interface states in the empty or in the filled state. Induced shifts in the C-V characteristics allow a direct access to both concentrations which are in the high 1011 cm−2 range. The energy density of interface states is calculated in two ways from the C-V plots and directly measured by deep-level transient spectroscopy. The energy density is equal to ∼1.1012 cm−2 eV−1 from Ec to Ec−0.6 eV and then increases to 7–8×1012 cm−2 eV−1 near Ec−0.7 eV.

    Preparation electrical properties and interface studies of plasma nitride layers on n-type InP (1991)

    Notizen: The growing conditions and the basic electronic and interface properties of InP-nitride-metal structures formed by indirect plasma-enhanced nitridation are reported. The deposited nitride layer PxNyClz is a NP polymer with a chemical composition close to P3N5 but with weak inclusions of H atoms. These nitride films are deposited at temperatures as low as 220–250 °C with growing rates of 50 A(ring)/min and stabilized by a post annealing at 300 °C in a reducing gaseous atmosphere. The optimized composition corresponds to Eg=5.5 eV, εr=6.2, n=1.95, a room-temperature resistivity ρ(approximately-greater-than)1013 Ω cm and a breakdown voltage Er(approximately-greater-than)5×107 V cm−1. The capacitance-voltage characteristics of Au-NP-InP diodes reveal that quasi-flat band and strong depletion regimes are reached, i.e., that the Fermi level in InP is swept through the entire upper half part of the electronic gap. These C-V characteristics are hysteresis free, and this allows a meaningful calculation of the interface states density Nis and of their energy distribution Dis(E). This interface states energy distribution Dis(E) is in the 1011 cm−2 eV−1 range and is very similar in magnitude to the ones observed at the InP-oxide or InP-sulfide interfaces despite the large differences in the growing atmospheres. The thermal stability of the InP-NP interface, as checked by inspection of the I-V and C-V curves, is good till 500 °C, this is at least 300 ° higher than with sulfides.

    Electronic configuration of cerium in amorphous alloys (invited; abstract) (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notizen: We have investigated the effect of structural disorder on the valence of cerium in different families of amorphous alloys prepared by coevaporation on to cryogenic substrates. The Ce electronic configuration was characterized by LIII x-ray absorption spectroscopy and bulk magnetization measurements. Special attention was paid to the amorphous analogs of prototypic Kondo and strongly mixed valent compounds in the crystalline state, such as Ce Si2 (TK(approximately-equal-to)200 K), CemNin, CemCon. The cerium was found to be purely trivalent in amorphous CexSi1−x (0≤x≤0.75) alloys over both the metallic and nonmetallic concentration ranges, so that the weakly mixed valent state in crystalline CeSi2 is believed to rely on details of the crystalline symmetry and band structure. In contrast, the cerium was found to remain mixed valent in amorphous CexCo1−x (0.15≤x≤0.75) and CexNi1−x (0.30≤x≤0.60) alloys, without any significant effect of the structural disorder. The concentration dependence of the Ce valence anomaly was found to be different in the Ce Ni and Ce Co alloys. This different behavior is discussed in terms of electronic band structure.

    Short-range effects on hyperfine fields in amorphous CoSn alloys (abstract) (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 3554-3554 
    Details
    ISSN: 1089-7550
    Quelle: AIP Digital Archive
    Thema: Physik
    Notizen: We have studied the 59Co and 119Sn hyperfine fields in amorphous CoSn alloys obtained by coevaporation onto cryogenic substrates. 59Co spin-echo spectra were measured at 1.4 K in zero-applied field on ferromagnetic Cox Sn1−x (0.65≤x≤0.80) alloys. NMR spectra display peaks. These peaks have a relative intensity which varies with composition, but their average location in frequency is concentration independent. From a comparison with 59Co NMR spectra in crystalline Co with dilute Sn impurities, it is inferred that the structures observed in NMR spectra for amorphous CoSn alloys are related to the number of Sn first neighbors of the Co resonant nuclei. Thus, short-range effects are thought to be predominant in determining the Co on-site moments in these alloys, as well as in amorphous Co alloys with other s-p elements. 119Sn Mössbauer spectra were measured at room temperature on paramagnetic Cox Sn1−x (0.40≤x≤0.55) alloys. Comparison is made with the stoichiometric CoSn crystalline compound, where quadrupolar interactions give rise to an admixture of two doublets corresponding to the two inequivalent Sn sites. Mössbauer spectra for the amorphous CoSn alloys display a single doublet identified as arising from Sn atoms in trigonal prisms arrangements. These results are discussed within the frame of current models for the structure of metallic glasses.

    Hydraulic architecture and water flow in growing grass tillers (Festuca arundinacea Schreb.) (2001)

    Notizen: The water relations and hydraulic architecture of growing grass tillers (Festuca arundinacea Schreb.) are reported. Evaporative flux density, E (mmol s−1 m−2), of individual leaf blades was measured gravimetrically by covering or excision of entire leaf blades. Values of E were similar for mature and elongating leaf blades, averaging 2·4 mmol s−1 m−2. Measured axial hydraulic conductivity, Kh (mmol s−1 mm MPa−1), of excised leaf segments was three times lower than theoretical hydraulic conductivity (Kt) calculated using the Poiseuille equation and measurements of vessel number and diameter. Kt was corrected (Kt*) to account for the discrepancy between Kh and Kt and for immature xylem in the basal expanding region of elongating leaves. From base to tip of mature leaves the pattern of Kt* was bell-shaped with a maximum near the sheath–blade joint (≈ 19 mmol s−1 mm MPa−1). In elongating leaves, immature xylem in the basal growing region led to a much lower Kt*. As the first metaxylem matured, Kt* increased by 10-fold. The hydraulic conductances of the whole root system, 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu1" location="equation/PCE_657_mu1.gif"/〉 (mmol s−1 MPa−1) and leaf blades, 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu2" location="equation/PCE_657_mu2.gif"/〉 (mmol s−1 MPa−1) were measured by a vacuum induced water flow technique. 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu1" location="equation/PCE_657_mu1.gif"/〉 and 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu2" location="equation/PCE_657_mu2.gif"/〉 were linearly related to the leaf area downstream. Approximately 65% of the resistance to water flow within the plant resided in the leaf blade. An electric-analogue computer model was used to calculate the leaf blade area-specific radial hydraulic conductivity, 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu3" location="equation/PCE_657_mu3.gif"/〉 (mmol s−1 m−2 MPa−1), using 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu2" location="equation/PCE_657_mu2.gif"/〉, Kt* and water flux values. 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu3" location="equation/PCE_657_mu3.gif"/〉 values decreased with leaf age, from 21·2 mmol s−1 m−2 MPa−1 in rapidly elongating leaf to 7·2 mmol s−1 m−2 MPa−1 in mature leaf. Comparison of 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu2" location="equation/PCE_657_mu2.gif"/〉 and 〈inlineGraphic alt="inline image" href="urn:x-wiley:01407791:PCE657:PCE_657_mu3" location="equation/PCE_657_mu3.gif"/〉 values showed that ≈ 90% of the resistance to water flow within the blades resided in the liquid extra-vascular path. The same algorithm was then used to compute the xylem and extravascular water potential drop along the liquid water path in the plant under steady state conditions. Predicted and measured water potentials matched well. The hydraulic design of the mature leaf resulted in low and quite constant xylem water potential gradient (≈ 0·3 MPa m−1) throughout the plant. Much of the water potential drop within mature leaves occurred within a tenth of millimetre in the blade, between the xylem vessels and the site of water evaporation within the mesophyll. In elongating leaves, the low Kt* in the basal growth zone dramatically increased the local xylem water potential gradient (≈ 2·0 MPa m−1) there. In the leaf elongation zone the growth-induced water potential difference was ≈ 0·2 MPa.
