Abstract
Optical measurements of bulk GaSb:S reveal the structure of the lattic e two phonon absorption and acceptor-valence band transitions. A sulph ur related local vibrational modes and several bands related to the op tical transitions from the ground state of the acceptor level are obse rved. A comparison of transport and optical measurements for GaSb:Te a nd AlGaSb:Te shows that in the alloy it is easier to obtain high conce ntrations of the electrically active Te impurity.
