Strain dependent electron drift velocity in Al 1– x In x N/AlN/GaN
We have measured the room‐temperature velocity–field characteristics in Al 1– x In x N/AlN/GaN strained structures ( x = 0.12, 0.15, 0.22) with two‐dimensional electron gas channels biased up to 200 kV/cm using nanosecond‐pulsed current–voltage technique. The drift velocity was estimated under assum...
