INVESTIGATION OF THE STRUCTURE OF THE CONDUCTION BAND OF KTaO3 BY THE SHUBNIKOV-DE HAAS EFFECT.

Abstract:

Measurements of Shubnikov-de Haas oscillations in the semiconducting perovskite KTaO//3 have been studied as a function of crystallographic orientation and temperature. The two oscillatory periods observed for all directions except B parallel (111) were found to correspond to ellipsoidal constant energy surfaces located at the X-point. The temperature dependence of the Shubnikov-de Haas amplitudes was used to determine effective masses, m//t equals 0. 61 m//o and m//1 equals 1. 4 m//o.

OBSERVATIONS OF CYCLOTRON RESONANCE AND THE MAGNETOPHONON EFFECT IN InAs1 -xPx COMPARED WITH THE PREDICTIONS OF k. p THEORY.

Inst Phys Conf Ser (1979) 1187-1190

Authors:

RJ Nicholas, RA Stradling, JC Ramage, JC Portal, S Askenazy

Abstract:

The effective mass of electrons in InAs//1// minus //xP//x has been determined as a function of alloy composition by cyclotron resonance and the magnetophonon effect. Comparison with k. p theory shows a reduction in the matrix element P**2 due to alloy disorder. Magnetophonon oscillations were observed due to both of the L. O. phonon modes present in the mixed crystals.
