摘要
InSb layers doped with Ag and Au were grown by directional solidification. The effective segregation coefficients of Au and Ag in InSb measured on samples grown at a rate of 2 cm/h were found to be 3.1 x 10(-2) and 1.2 x 10(-3), respectively. The electrical properties of the layers and the effective lifetime of photogenerated carriers were measured at 77 and 300 K. The effective lifetime is correlated with the specific surface area of the samples.
