Abstract
Electrical conductivity and Hall effect are measured for p-type specimens of polycrystalline GaSb.InSb with impurity concentration about 1017 cm.−3. Analysis of these data suggests that μn/μp = 11, and that the intrinsic gap varies linearly with temperature from 0.265 ev. at 0° K. Measurement of the photoconductive limit at various temperatures shows that the gap widens on heating, though the electrical data seem difficult to reconcile with the large gradient of +1.1 × 10−3 ev./°C. indicated by the optical data.
