Abstract

Infrared absorption spectra of proton and deuteron implanted InP single crystals exhibit four localized vibrational modes with frequencies of 2197, 2212, 2308, 2335 cm^-1 and 1600, 1619, 1659, 1678 cm^-1, respectively. From a comparison of these mode frequencies with those in other species containing In-H(D) and P-H(D) bonds it is concluded that all four modes observed are due to stretching vibrations of bonds formed between phosphorus and the implanted atoms. The number of vibrating bonds is found to be proportional to the damage density. Annealing experiments indicate a higher thermal stability of the defect configurations giving rise to the two high-energy localized modes.

Electronic and structural properties of hydrogen on semiconductor surfaces
1991, Physica B: Physics of Condensed Matter
In this paper we will review the scientific literature which addresses the atomic geometry and electronic structure of clean and hydrogenated semiconductor surfaces. In particular, results related to vibrational studies will be presented. First, surfaces of elemental semiconductors (Ge, Si), Ge/Si-alloys, and III–V compound semiconductors chemisorb in a first stage atomic hydrogen by saturating surface atom dangling bonds. In a second step surface bonds are broken and a change of the geometrical structure results. Finally, higher hydrogen exposures are able to etch semiconductor surfaces. Best understood to date are surfaces of Si(1 0 0), Si(1 1 1), Ge_xSi_1−x(1 0 0), and III–V's after cleavage which have been modeled by dimerized and undimerized structures. (1 0 0) surfaces of III–V semiconductors, like GaAs and InP, tend to be dimerized, too.
Hydrogen implantation in semiconductors
1991, Physica B: Physics of Condensed Matter
Proton implantation is presented as a versatile tool for hydrogen-doping of semiconductors. The paper shows the advantages as well as disadvantages of this technique: precise spatial distribution and hydrogen concentrations obtained up to the non-equilibrium states are possible because of the damages introduced during the slowing down of protons. Some examples of experimental results obtained by proton implantation are discussed in detail. The review is also intended to serve as a source of key references in the field.
Chapter 4 Hydrogen Passivation of Damage Centers in Semiconductors
1991, Semiconductors and Semimetals
This chapter describes the hydrogen passivation of damage centers in semiconductors. It presents an analysis of specific defect centers in semiconductors. Hydrogen aids the motion of dislocations in Si, which can lead to enbrittlement. The chapter discusses the involvement of oxygen in processes that are attributed to hydrogen and the role of H in defect formation. Electrical studies show that H neutralizes defects at relatively low temperatures, suggesting that H is very mobile at low temperatures. The various defect centers in III–V materials appear to be affected by H. From infrared absorption (IR) vibrational absorption experiments, there is a multitude of vibrational bands in Si that contain H far more than the modes attributable to Si–H, Si–H₂, and Si–H₃. The presence of oxygen causes the broadening and overlapping of some of these modes, hindering their interpretation. Vibrational bands above 2000 cm^–1 are attributed to vacancy related defects, while those below 2000 cm^–1 tend to be interstitial-related. Many insights have been gained from IR vibrational spectroscopy in III–V compounds that pertain to P–H, Ga–H, and As–H modes. Also, new insights are being stimulated by the observation that H neutralizes the EL2 and DX centers.
Chapter 13 Neutralization of Defects and Dopants in III-V Semiconductors
1991, Semiconductors and Semimetals
This chapter describes the neutralization of defects and dopants in III–V semiconductors. The chapter presents a review on the effects of hydrogen (H) in III–V semiconductors. In GaAs, the neutralization of silicon (Si) donors reduces the concentration of free electrons but increases the mobility of the remaining electrons. The H-donor complex is stable to 250°C. Evidence that H bonds directly to donor impurities is provided by the observation that the dissociation energy scales with the H-donor bond strength; the dissociation energy for the Si–H complex is 2.1 eV. In photoluminescence, the hydrogen neutralization of dopants is manifested by the disappearance of bound excitons. In GaAs, acceptor-H complexes are less stable than donor-H complexes. Some hydrogenation techniques may induce surface damage that increases the H concentration at the surface. Some of the compounds tend to decompose during hydrogenation—for example, the surface of indium phosphide (InP) decomposes with the formation of phosphine (PH₃). This problem has been controlled by encapsulating the substrate with a hydrogen-permeable layer.
Localized vibrational modes in proton and deuteron implanted GaP single crystals
1990, Solid State Communications
Infrared absorption spectra of proton and deuteron implanted GaP single crystals reveal two hydrogen induced modes with frequencies of 1839 and 2204 cm⁻¹ and six deuterium induced modes with frequencies of 1260, 1295, 1333, 1602, 1635 and 1670 cm⁻¹. From a comparison of these mode frequencies with those reported for proton and deuteron implanted GaAs and InP single crystals it follows that vibrating defects with both GaH(D) and PH(D) bonds are formed. The number of vibrating centres is found to be proportional to the damage density.
Hydrogen vibrations in ZnSe
1988, Solid State Communications
We report new and strong localized vibrational modes in proton and deuteron implanted zinc selenide at about 1315 and 950 cm⁻¹, which we ascribe to ZnH/D vibrations. The values of the oscillator strengths obtained for these lines are 0.17 and 0.15, respectively. Comparison of our data with the previously published results shows that in our experiments much more hydrogen is retained in the samples, probably due to better experimental conditions during irradiation.
