  • Abstract
    The frequency limits in intrinsic fT of the nano-scale HEMTs with various channel materials are investigated by using the quantum-corrected Monte Carlo simulation. The device C with the InSb channel exhibits the higher intrinsic fT from the lower Vds because of the higher electron velocity. Owing to the shorter limit in the Lg scaling at the lower Vds, the device C also exhibits the higher frequency limit in the intrinsic fT, indicating its potential for the low power and THz operation.
