Abstract

he paper concerns the possibility of using CW (continuous wave) CO2-laser annealing (λ=10.6 μm, P≤ 100 W/cm2) for formation of a barrier in the Al/a-Si:H/SS (SS-stainless steel) structures with good rectifying I V characteristics. The infrared absorption spectra, photoelectric properties, temperature effect on the conductivity and saturation current were analyzed and various contact models are discussed.
