沈学础 %A 叶红娟 %A 康荔学 %A 陶凤翔 %J 物理学报 %D 1985 %I %X We report here the results of far infrared absorption on spectra of mixed crystal Cd1-xMnxTe with different compositions x in wavenumber region of 20 to 400cm-1 and temperature region of 4.2 K to 300 K. The CdTe-like, MnTe-like reststrahlen bands and their LO-TO splitting have been resolved. A low frequency absorption band for all the samples and a quasi-local mode absorption peak for the sample with low x value have been found for the first time in the low frequency side of reststrahlen band. In addition, several two-phonon bands have also been observed on both sides of reststrahlen band. The appearence and the position of the quasi-local mode have been estimated with the lattice dynamics of defects. Other absorption bands and their probable origin have also been discussed. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=886B0386098291AFC90D8DEB0A4893D9&yid=74E41645C164CD61&vid=339D79302DF62549&iid=59906B3B2830C2C5&sid=ECF40C1D1FB7C43B&eid=1593278DEEDA4D8F&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=0
