Abstract

The 2 K photoluminescence of n- and p-type GaSb Is compared. It is shown that in both cases several emission lines can be explained by the existence of a doubly ionizable acceptor (ionization energies of 34.5 and 102 meV). This acceptor was found to be always present in GaSb. Evidence is presented that donors participate in a transition involving the first ionization state of this acceptor (even in undoped samples). The ionization energies of two other acceptors are determined to be 57 and. 13 meV. The (LO) -phonon replicas (hwLO≈ 30 meV) of several transitions have been observed.
