Simulating Pseudomorphic HEMTs: Optimizing Performance to Achieve Multi-terahertz Operating Frequencies

In summary, we show that properly scaled HEMT devices can operate will into the THz regime, and provide a viable device option in this spectral region. These results are also important for logic devices desired for operation in the Tbs regime, as the cutoff frequency f

is intimately related to the logic delay time in a switching transistor.
