The Study of C Factor Mixed with TiO_2 Electric Structure and the First Nature Theory in the Optics Natures

We caculated the geometry,electric and optic structures of factor C mixed with TiO2 crystal on the basis of the first nature of DFT,the way of plane wave and ultrasoft pseudopotential.We found forbbiden band width decreased because of the mixture of factor C.From the analysis combined with density of states,we worked out the physical mechanisms of the decreasing of forbbiden band width,stated the optic nature of the material after mixing,raised the potential application of factor C mixed with TiO2 system in components area.
