| Abstract(in English) | Dynamics of photo-generated carrier of CVD diamond films were mesured with ultra-fast pump-probe method. Dependence of pumping laser wavelength on carrier lifetime and variation of carrier lifetime inside grain were observed. In the case of longerwavelength (384nm) and smaller grain size film, the shortest lifetime of 2.5ps was obtained, while larger than 60～80ps lifetime was with shorter wavelength pumpingand larger grain size samples. The drastically decreasing of the carrier lifetime was also observed near the grain boundary in singlegrain of polycrystalline diamond film. These results denoted that the grain boundary play a important role to reduce the carrier lifetime. |
