摘要
本文给出闪锌矿结构中替位杂质的声子谱。系统分析了杂质诱发的局域模,禁带模和共振模的形成规律及特性。除了TA带上方的准局域模外,还发现了在TA声学带下方的新的低频共振模式。
The phonon spectra of substitutional impurities in zincblende structure are calculated. The form law and characteristics for imparity induced local modes, gap modes and resonant modes are analyzed systematically. Besides the quasi-local mode above TA acoustic band, we also find a new low frequncy resonant mode just below TA acoustic band.
