摘要：
Heavily compensated GaSb (2-in.-diameter substrates) with resistivity as high as 7 X 10(3) Omega-cm, corresponding to a net donor concentration of 3.5 X 10(13) cm(-3) at 77 K, and 16.4 Omega-cm, corresponding to net donor concentration of 1.16 X 10(16) cm(-3) at 300 K, have been obtained by tellurium (Te) compensation in vertical-Bridgman-grown bulk crystals. Very interesting p- to n-type as well as n- to p-type changes have been observed as a function of temperature in these samples.
