InP/InGaAs Heterostructure Bipolar Transistors Grown at Low Temperature by Metalorganic Chemical Vapor Deposition

Abstract
We describe the performance of InP/InGaAs heterostructure bipolar transistors (HBTs) grown at low temperature by metalorganic chemical vapor deposition (MOCVD). HBTs with a base thickness of 70 nm and doping level of 1×1019 cm-3 show excellent current gain characteristics (current gains h FE>300, ideality factors n B17 cm-3.
