MBE Growth and Optical Properties of GaN, InN, and A3 B5 Nanowires on SiCSi(111)‎ Hybrid Substrate

Abstract EN

The possibility of GaN, InN, and A3B5 nanowires MBE growth on a silicon substrate with a nanoscale SiC buffer layer has been demonstrated.

Optical studies indicated a higher structural quality GaN NWs compared with the best structures of GaN NWs without silicon carbide buffer layer.

The diameter of A3B5 NWs is smaller than diameter of similar NWs which were grown on a silicon substrate, because of higher lattice mismatch.

In particular, InAs NWs diameter was evaluated as little as 10 nm, one of the smallest ever demonstrated for this NWs system.
