摘 要:Hydrogenated nano-crystalline silicon (nc-Si∶H) film is of much higher light absorption coefficient than that of mono-crystalline silicon (c-Si), and exhibits better electrical transport characteristics and higher resistance to the light-induced degradation than that of hydrogenated amorphous silicon (a-Si∶H) film. These remarkable photoelectric properties make nc-Si∶H film being widely applied in solar cells and thin film transistors, and the modifications of nc-Si∶H film on the structure and properties have attracted much attention. However, the modification of nc-Si∶H films with ion irradiation has not yet been well studied.
