Abstract

AbstractThe presence of light and heavy holes in GaSb has been pointed out by Becker et al.[1] and values of their effective masses have been obtained by various authors [2,3,4]. A study is made here of the Hall effect, and the longitudinal and transversal magnetoresistance of p‐type GaSb crystals at 4.2 °K, from 0 to 33 kG. Assuming that depopulation of the light‐hole band by the field is mainly responsible for the variation of the Hall coefficient and considering isotropic bands tangential at k (000), the densities, mobilities, and effective masses of the two species of holes are deduced.
