Abstract : This program is directed towards the monolithic integration of resonant tunneling diodes (RTDs) and conventional heterostructure transistors, and the demonstration of high speed, low power, high functional-density circuits. This effort was carried out in close collaboration with MIT Lincoln Laboratory (LL). This team demonstrated lattice mismatched InGaAs/AlAs RTDs with high peak to valley current ratio (PVCR) and high current density capability, integrated with AlGaAs/Ga-As-based heterojunction bipolar transistors (HBTs) and hetero-structure field effect transistors (HFETs). We explored by simulation and experiment several novel digital integrated circuit approaches, based on this technology.
