【摘要】 采用傅里叶变换红外光谱仪，在４．２～３００Ｋ、２０～３５０ｃｍ－１范围测量了Ｈｇ１－ｘＣｄｘＴｅ的远红外透射光谱，研究了剩余射线吸收带两侧样品的吸收行为．除了单声子及双声子模外，还观察到杂质能级和由杂质导致的振动模更多还原

【Abstract】 The vibrational modes in Hg 1- x Cd x Te epitaxial films were investigated by means of far infrared transmission spectra at temperatures from 4 2 to 300K.The observations were put forward in the spectral range from 20cm -1 to 350cm -1 , emphasizing the wavenumber region at the low frequency side of the reststrahlen absorption band.A series of single phonon and two phonon modes, defects induced vibrational modes and impurities levels were observed.更多还原
