Abstract
In the present paper we review some of the present technologies of interest for terahertz (THz) applications, and the physics and modeling of ultra-high frequency devices such as high electron mobility transistors (HEMTs) which have achieved THz frequencies. We present results of full band Cellular Monte Carlo (CMC) physics based simulation of InP and GaN based HEMTs of current interest to industry, and in particular, we address the current limitations in their frequency response in terms of the material and device structure, and the ultimate limits of scaling for such technologies.
