    SECTION: Metal-semiconductor field-effect transistors
    To improve the performance of the MESFET, various heterojunction field-effect transistors (FETs) have been developed. A heterojunction is a junction formed between two dissimilar semiconductors, such as the binary compound GaAs and the ternary compound AlxGa1 − xAs. Such junctions have many unique features that are not readily available in the...
