High-temperature (673-1173 K) electrical property (#sigma#, R_H) measurements in undoped and In-doped (up to 1 X 10~20 at/cm~3) CdTe were performed under different stoichiometric conditions. Cadmium (tellurium) vapor pressure or temperature electron (hole) density dependences were obtained. The results are described by a computed defect structure model, which optimizes the defect reaction constants. A new In incorporation defect reaction is proposed, explaining the dopant self-compensation mechanism. direct c 1999 Elsevier Science B.V. All rights reserved.
