Description
Optical properties and dark current activation energy of hydrogenated amorphous silicon (a,Si:H) produced by the expanding thermal plasma chemical vapour deposition (ETPCVD) technique are investigated as a function of substrate temperature in the 150,500°C temperature range. The optical transmission spectra were used to obtain the thickness, refractive index, and optical band gap of the a, Si:H films. It is observed that while the refractive index is increasing with substrate temperature, the optical band gap and deposition rate, as well as the dark conductivity activation energy, are decreasing.
