摘要

InP and GaN crystals were irradiated by swift heavy ions(SHI,56Fe and 209Bi)with kinetic energies of 6.3 and 9.5 MeV/u and highly charged ions(HCI,1.4 MeV 86Kr^12+and 114Xe^20+).The irradiation effects induced by different types of irradiation were studied by Raman spectroscopy.Two new irradiation-induced vibrations observed at 294 and 338 cm^-1 as shown in Fig.1 are assigned to InP-like TO and LO first-order optical modes[1],respectively,and in Fig.
