We present calculations of phonon scattering in zincblende (ZB) and wurtzite (WZ) AlGaN/GaN quantum-well heterostructures. In the Block-Gruneissen (BG) and equipartition (EP) regimes, we take into account many-body effects. Dependences of the mobility on the temperature and the electron density for both ZB and WZ GaN are presented, and it is shown that the WZ mobility is higher than the ZB mobility.
