The article reports the results of study of n–GaSb〈Te〉 specimens with plain ohmic contacts and demonstrates that at T > 50°C the studied structure generates current (up to 0.4 nA at T = 200°C) and voltage (up to 0.4 mV at T = 210°C). These phenomena are attributed to thermally stimulated decomposition of “shallow donor + vacancy” complexes with subsequent formation of periodic distribution of concentration of vacancies and shallow donors over the specimen length.
