Abstract. In 1969 Chittick et al [1] discovered that hydrogenated amorphous silicon (a-Si:H) deposited from SiH 4 glow discharges is a semiconductor, and in 1975 Spear and LeComber [2] demonstrated that a-Si:H could be doped by adding B 2 H 6, AsH 3 or PH 3 to SiH 4.This opened the possibility of making thin-film devices at low temperature (100–300°C) on glass substrates for various ...
