AlGaN/GaN MBE 2DEG heterostructures : interplay between surface-, interface- and device-properties
Due to their wide band gap and high bond strength, the III-N semiconductors can be used for violet, blue and green light emitting devices as well as for high temperature and high power transistors. In comparison to conventional AlGaAs/GaAs heterostructures the AlGaN/GaN material system offers new …
