In this paper, the properties of silicon carbide films obtained on porous silicon substrates by the substitution method of atoms are considered. Silicon carbide films are obtained on macroporous Si (100) substrates, and porous surfaces «envelop». This structure can find application in the manufacture of electrodes for supercapacitors. Polycrystalline 3C-SiC silicon carbide films with a grain size of 27 nm were obtained on mesoporous Si (100) substrates. Single-crystal epitaxial 3C-SiC silicon carbide films obtained on mesoporous Si (111) substrates have a small contact area between Si and SiC and can effectively «untie» mechanical stresses arising from differences in the thermal expansion coefficients and parameters of the silicon and silicon carbide lattice. It was found that the presence of pores in the near-surface Si layers leads to considerable stress relaxation in SiC films, which opens the way to the growth of thick GaN layers on the SiC/porous-Si/Si template. |
