摘要：

We have investigated the heteroepitaxial growth of 3C-SiC on Si by low pressure chemical vapor deposition (LPCVD) using a silane-propane-hydrogen reaction gas system. By the growth at low pressure below 10 Torr, several problems arising from atmospheric pressure CVD (APCVD) were solved, namely the growth of protrusions was suppressed and thickness uniformity was improved. Moreover, atomically flat surfaces were obtained. Although the growth temperatures in the case of LPCVD were lower than those in the case of APCVD, LPCVD epilayers showed excellent crystallinity and luminescence properties, comparable with those of APCVD epilayers.
