Study of SiC polytype heterojunctions

Ab initio calculations of some electronic and elastic properties for SiC polytypes

“…All this enables one to consider SiC as a very interesting material for industrial applications and represents a strong motivation for its theoretical studies. In particular, the exploration of electronic [3][4][5][6][7][8][9][10] and mechanical properties [11], specifically the elastic ones [12][13][14][15][16][17][18][19][20][21][22][23][24][25], look rather important for future engineering applications.…”

Polytype inclusions and polytype stability in silicon-carbide crystals

“…It is known that transformation of the polytype leads to a stop in the propagation of threading screw dislocations already present in the crystal by varying the defect structure in the ingot [11,2]. In addition, a programmed change in the polytype can basically form (on the basis of silicon carbide) so-called heteropolytype compositions, i.e., unstressed epitaxial structures, including those with a two-dimensional electron gas [57,58].…”
