Abstract
We have studied the influence of metamorphic-buffer layer design on the temporal (storage) stability of electrical characteristics of InGaAs/GaAs metamorphic high-electron-mobility transistors (MHEMTs). Using measurements of the Hall effect, it is established that transistor heterostructures with a metamorphic buffer based on In(Al)GaAs/InAlAs superlattices possess maximum values of the concentration and mobility of electrons in the MHEMT channel and show minimum susceptibility to temporal degradation.
