Materials and Device Characteristics of Pseudomorphic AlGaAs-InGaAs-GaAs and AlInAs-InGaAs-InP High Electron Mobility Transistors
Published online by Cambridge University Press: 28 February 2011
Abstract
High electron mobility transistors (HEMTs) with single quantum well active layers composed of pseudomorphic IπGaAs grown on GaAs and InP are establishing new standards of performance for microwave and millimeter wave applications. This is due to recent progress in the molecular beam epitaxial growth of strained InGaAs heterostructures coupled with developments in short gate length (sub%0.2 µm) device fabrication technology. This paper reviews this progress and the current state-of-the-art for materials and devices.
