    Abstract:
    GaInAs-AlInAs HEMTs have improved DC and RF performance as compared with GaInAs-(AlGa)As HEMTs. The drain-source I-V characteristics exhibit a kink related to trap ionization in the AlInAs buffer. This kink is eliminated by using a GaInAs buffer. Sidegating is also dramatically reduced with the GaInAs buffer
