Abstract
Experimental studies of the donor-impurity excitation spectra in InSb in high magnetic fields have yielded good qualitative agreement with theoretical predictions with regard to transition energies, selection rules, polarization, and absorption constants. Quantitatively, the data demonstrate the need for including the effects of nonparabolicity in the theory, and indicate that corrections to the calculated ground-state energy are required. The usefulness of optical experiments in studying carrier freeze-out effects is briefly discussed.Keywords
