摘要：
The authors show that the electron mobility can be strongly enhanced in AlN/GaN/AlN heterostructures with the shallow InxGa1-xN channel-nanogroove-in the middle of the potential well. The modified heterostructure has the room-temperature electron mobility, which is five times larger than that in conventional quantum wells. The maximum mobility enhancement is achieved for In content x approximate to 0.05, which is sufficient to weaken the intersubband electron scattering without leading to the substantial electron-interface-phonon scattering. The mobility enhancement is pronounced for a wide range of the carrier densities (10(11)-10(13) cm(-2)), which is important for GaN technology. (c) 2006 American Institute of Physics.
