InGaAs/InAlAs heterostructure is realized on GaAs substrate. This GaAs-based metamorphic high electron mobility transistor (mHEMT) heterostructure can reduce the stress at the interface between heterostructure and GaAs through the gradual change of In composition. Such a mHEMT structure can provide device performance that is [...]
