Semiconductor heterojunction devices based on SiC

摘要

A Si(1-x)MxC material for heterostructures on SiC can be grown by CVD, PVD and MOCVD. SIC doped with a metal such as Al modifies the bandgap and hence the heterostructure. Growth of SiC Si(1-x)MxC heterojunctions using SiC and metal sources permits the fabrication of improved HFMTs (high frequency mobility transistors), HBTs (heterojunction bipolar transistors), and HEMTs (high electron mobility transistors).
