Study of the Processes of Mesoporous-Silicon Carbonization

详细

Experimental and theoretical studies of the processes of mesoporous-silicon carbonization during the formation of buffer layers for the subsequent epitaxy of 3C-SiC films and related wide-gap semiconductors are performed. Analytical expressions for the effective diffusion factor and diffusion length of carbon atoms in a porous system are obtained. The proposed model takes into account the processes of Knudsen diffusion, coagulation and the overgrowth of pores during the formation of a silicon-carbide layer.
