| 中文摘要 | We report Raman analysis of A(1)(LO) (longitudinal optical) and E-2(high) phonon lifetimes in a bulk GaN single crystal and their temperature dependence from 77K to 770 K. Both the A(1)(LO) and E-2(high) phonons in GaN were observed decaying primarily into two phonons of equal energy [Klemens model, P. G. Klemens, Phys. Rev. 148, 845 (1966)]. This is a rare example of a high-quality free-standing GaN bulk single crystal displaying abnormal A(1)(LO) phonon decay. These results will have significant impact on designing and understanding of GaN-based high-speed, high-power electric devices. (C) 2013 American Institute of Physics.
