The local environment of Ga, Se and Tl atoms in InTe-based solid solutions
was studied by EXAFS technique. It was shown that all investigated atoms ar
e substitutional impurities, which enter the In(1), Te and In(2) positions
in the InTe structure, respectively. The electrical measurements revealed t
hat In1-xGaxTe and InTe1-xSex solid solutions become semiconductors at x >
0.24 and > 0.15, respectively. (C) 2000 Elsevier Science Ltd. All rights re
