摘要：
SnSe and SnSe2 are known p-type and n-type semiconductors respectively. Following an earlier report on the lamellae-structured SnSe-SnSe2 eutectic alloy, thin films of this alloy have been prepared. The films exhibit p-type conductivity. From the optical absorptance data, their band gaps have been evaluated and studied as functions of the film thickness and deposition temperature. The data indicate absorptance through indirect intraband transition with a band gap around 1.1eV. The detailed results are reported.
