The optical properties of silicon carbide thin films

Jun 19, 2019· Although the optical band gap of crystalline SiC thin film is reported to be about 2.4 eV , the optical band gap of hydrogenated amorphous SiC (a-SiC:H) thin film can be adjusted by changing the carbon and hydrogen content as well as the microstructure of the film [4–8]. This ability has made a-SiC:H thin film an interesting controllable material for optoelectronic appliions.
