摘要
Hydrogenated amorphous silicon (alpha-Si:H) films were prepared by remote plasma chemical vapor deposition (RPCVD) using SiH4/SiH2Cl2/He/H-2 mixtures. With increasing Cl content in alpha-Si:H up to about 10(19) cm(-3), the stablity of photoconductivity under light illumination was improved with keeping the defect density and Urbach energy constant. We deposited hydrogenated amorphous silicon films with hydrogen content of 6 at. %, Cl content of similar to 10(19) cm(-3), and defect density of 3x10(15) cm(-3), which exhibited very small photoconductivity degradation under light illumination. The optimum Cl concentration in alpha-Si:H for stable alpha-Si:H appears to be similar to 10(19) cm(-3). (C) 1995 American Institute of Physics.
