    Notes: Abstract The transmitted energy density in thin single Si crystal, wafers is measured atλ=1.06 μm as a function of the incident energy density for a Nd laser pulse of 30 ns duration. Non-linear effects begin to become important at about 0.3 J/cm2. The contribution due to free-carriers is separated from the interband one by using measurements made at low energy density and at different sample temperatures in the 20°–150 °C range. The time dependence of the free-carrier concentration and of the lattice temperature is computed for different values of the Auger constant. The experimental data in the 0.2–2.5 J/cm2 energy density range are fitted with an Auger constant of 10−30 cm6s−1.

    Notes: Abstract Adsorption of copper, gold and beryllium on (110), (100), and (211) single-crystal planes of tungsten leads to essentially different work-function changes. It is known from numerous investigations of alkali-metal adsorption on metal substrates that the work-function variation reflects the electronic processes occurring during the formation of the adlayer. It is obvious that copper, gold and beryllium adsorption is accompanied by a wide variety of physical processes different from those appearing in alkali-metal adsorption. The existing experimental data concerning work-function changes induced by copper, gold and beryllium adsorption are compiled. A model is developed, which may explain these changes.

    Notes: Abstract The kinetics of the Staebler-Wronski effect ina-Si:H were investigated experimentally. The rate of recovery from the illuminated state B to the annealed state A was observed at various temperatures in undoped,n- andp-dopeda-Si:H. The data can be characterized by a thermally activated relaxation time with an activation energy decreasing with increasing doping concentration. The results are compared with previous data and existing models.

    TEM image contrast from antiphase domains in GaAs: Ge(001) grown by MBE (1984)

    Notes: Abstract Antiphase domains occur in thin GaAs epitaxial films grown on Ge(001) by molecular beam epitaxy. The domains have been imaged by transmission electron microscopy using 200-type reflections in dark field. The carefully chosen imaging conditions with convergent illumination ensure that doubly diffracted beams from a pair of first order Laue zone discs contribute to the singly diffracted 200-type beams. The three Bragg reflections may add in or out of phase to give domains in either light or dark contrast depending on their polarity.

    Characterisation of the interface between GaAs: Cr substrates andn-type epitaxial GaAs layers by infrared multiple interference analysis (1984)

    Notes: Abstract Infrared reflectivity measurements on vapour phase grownn-GaAs epitaxial layers (n=7×1016...5×1018 cm−3) deposited on semi-insulating GaAs:Cr substrates show interference structures whose strength cannot be explained by the interference pattern of a simple two layer system. Assuming a third very thin (0.4 μm) interfacial layer it is possible to describe the experimental results. For Te doping the carrier concentration in the interfacial film is higher than in the volume of the epitaxial layer; it is lower for Sn doping. The results of this nondestructive optical method were confirmed by conductivity measurements while etching the sample. The origin of the interfacial layer is discussed in terms of non-steady state conditions at the beginning of the epitaxial growth.

    Harmonic mixing in a cosine potential for arbitrary damping (1984)

    Notes: Abstract Harmonic mixing of two alternating electric fields due to a Brownian charged particle in a nonlinear one-dimensional potential of cosine shape is investigated. The dynamics of the system are described by a time dependent Fokker-Planck equation. The appropriate distribution function is obtained by a matrix continued fraction expansion method, which is treated numerically. The dc signal due to mixing is computed for strong thermal fluctuations in all relevant parameter ranges of the pinning potential strength, damping and frequency. The dc signal without fluctuations is discussed separately. Resonance effects are shown in the electric dc field and the additional phase shift, caused by intrinsic relaxation processes.

    Notes: Abstract Crystalline samples of Si, GaAs, GaP, InP, and CdTe have been rendered amorphous by bombardment with rare gas ions. DC conductivity and thermopower have been measured as a function of temperature in the interval between 15–500 K. In all cases, electron transport at low temperatures is characterized by non-simply activated processes of the hopping type transport, whereas band transport is observed at higher temperatures. The common and individual features of the different amorphous systems are discussed within the framework of existing transport theories.

    Dynamic RHEED observations of the MBE growth of GaAs (1984)

    Notes: Abstract Detailed measurements have been made of the specular beam intensity in RHEED patterns from static and growing GaAs surfaces. The basic parameters investigated were substrate temperature and electron beam azimuth. The results have provided further understanding of growth dynamics and surface disorder, respectively. There is a significant trend away from two-dimensional growth at the higher temperatures, which also correspond to more Ga-rich surface structures. Conversely, surface disorder is apparently greater during growth at the lower temperatures, where the structure is As-rich. The static As-stable 2×4 surface is, however, the most ordered and the most closely two-dimensional. It has also been shown that ordered, two-dimensional growth can be initiated from excess Ga adatom populations.

    Notes: Abstract Germanium films have been rf sputter deposited on a variety of substrates. A new techniques has been developed to control doping concentrations of the films at predetermined levels for bothp-type as well asn-type films. The hole concentrations of these films could be varied from 1015 to 2×1018/cm3 while the electron concentrations could be varied from 1015 to 5×1017/cm3 using this technique. Transmission electron microscope studies have been made to study the crystalline quality of the films.

    Formation of palladium silicide by rapid thermal annealing (1984)

    Notes: Abstract The formation of palladium silicide Pd2Si by rapid thermal annealing of Pd layers on silicon has been studied as a function of annealing time (1–60s) in the temperature range 350–500 °C. It is shown that the results found for conventional furnace annealing (long duration, low temperature) can be extrapolated for rapid thermal annealing (shorter time, higher temperature) when taking into account the exact time dependence of the short temperature cycle. The growth rate is essentially diffusion limited and the activation energy is close to 1.1±0.1 eV. Silicide resistivity of about 30–40 Ω cm was obtained for 200–400 nm thick Pd2Si layers formed at 400 °C for a few seconds.
