The possibility of InAs nanowires MBE growth on silicon (111) substrates with a nanometer buffer layer of silicon carbide has been demonstrated for the first time. The NWs diameter turned out to be smaller than on the silicon substrate - the minimum of NWs diameter was less than 10 nm. In addition, dependence of structural properties of InGaAs nanowires on composition was studied.

The nanowire samples were grown under the support of Russian Science Foundation (Project No 14-12-00393). This work was partially supported by RFBR (grant 16-29-03113 ofi_m).
