Abstract

The bands and densities of states of d bands in indium antimonide (InSb) are determined taking into account and disregarding the spin-orbit interaction. It is established that taking into account the effect of spin-orbit interaction results also in a substantial change in the dispersion of the obtained bands instead of only in the doublet splitting of the band of core d levels at ∼(0.79–0.86) eV. It is established that it is indium 4d states with e{sub g} and t{sub 2g} symmetry that give the main contribution to the density of states. The calculations are carried out by the LAPW method with the exchange-correlation potential in the generalized gradient approximation (LAPW + GGA)

Four-wave mixing in indium antimonide

Journal Article MacKenzie, H; Hagan, D; Al-Attar, H - IEEE J. Quant. Electron.; (United States)

The authors report a range of experiments in both the degenerate and nondegenerate regimes of four-wave mixing in indium antimonide using CW CO laser sources. For the degenerate case, they specify all the polarization source terms and the signals which they radiate. They identify the dominant term for the phase-conjugate signal experimentally, and confirm that this involves a large-period grating formed by the forward pump and probe. The third-order susceptibility was measured as chi/sup (3)/ approx. = 1.1 esu. This was shown to be highly resonant with the InSb bandgap. By varying the pump-probe input angle, the period of themore »« less

First-principles study of electronic structure and Fermi surface in semimetallic YAs

Journal Article Swatek, Przemys?aw - Computational Materials Science

In the course of searching for new systems, which exhibit nonsaturating and extremely large positive magnetoresistance, electronic structure, Fermi surface, and de Haas-van Alphen characteristics of the semimetallic YAs compound were studied using the all-electron full-potential linearized augmented-plane wave (FP–LAPW) approach in the framework of the generalized gradient approximation (GGA). In the scalar-relativistic calculation, the cubic symmetry splits fivefold degenerate Y-d orbital into low-energy threefold-degenerate and twofold degenerate doublet states at point around the Fermi energy. Furthermore one of them, together with the threefold degenerate character of As-p orbital, render the YAs semimetal with a topologically trivial band order andmore »« less

Physicochemical behavior of thallium in indium antimonide

Journal Article Evgen'ev, S; Sorokina, O; Zinovi'ev, V - Inorg. Mater. (Engl. Transl.); (United States)

This paper reports the physicochemical factors involved in the interaction components in the ternary system In-Sb-Tl and the effect of thalliu on indium antimonide properties. It is shown that ternary compounds are not formed in the In-Sb-Tl quasi-binary cross section. Despite the indium and thallium being closely related group III elements with similar electron configurations and tetrahedral covalent radii, the indium antimonide region of homogeneity in the In-Sb-Tl system, drawn along the quasi-binary InSb-Tl cross section, was only slight (0.2 at. % Tl).
Low frequency pressure modulation of indium antimonide

Journal Article Hallock, Gary; Meier, Mark - Review of Scientific Instruments

A lumped parameter resonator capable of generating megapascal pressures at low frequency (kilohertz) is described. Accelerometers are used to determine the applied pressure, and are calibrated with a piezoelectric sample. A laser diagnostic was also developed to measure the pressure in semiconductor samples through the band gap pressure dependence. In addition, the laser diagnostic has been used to measure the attenuation coefficient {alpha} of commercially available indium antimonide (InSb) wafers. The resonator and laser diagnostic have been used with InSb samples to verify the pressure response.

Influence of electron irradiation on the electrical properties of and recombination in indium antimonide

Journal Article Zaitov, F; Polyakov, A - Sov. Phys. - Semicond. (Engl. Transl.); (United States)

An investigation was made of the influence of room-temperature irradiation with electrons of energies 1, 4.5, 15, and 25 MeV on the electrical properties and recombination of excess carriers in n- and p-type indium antimonide. Such irradiation resulted in inversion of the type of conduction in p-type InSb. The same effect was produced by irradiation with 25 MeV electrons at 77/sup 0/ K followed by annealing at room temperature. An attempt was made to establish a correlation between the rate of introduction of defects by the bombarding electrons of various energies and the number of atoms displaced elastically by thesemore »« less
