报道了用光谱的手段研究 Si C纳米棒 (NR)的结果 .对于在实验中观察到 L O模的大幅度红移及新出现的喇曼峰 ,认为在类似 Si C NR的存在大量缺陷的极性纳米材料中 ,结构缺陷对材料特性的影响比量子限制效应更为重要 .理论计算证实了这一点 ,并解释了实验观察到的异常现象
The results of spectroscopic studies of Si C nanorods (NR) have been reported.For the significant redshift and emerging Raman peaks of the LO modes observed in experiments, it is believed that in the case of Si C NR-like electrodes with a large number of defects In nanomaterials, the effect of structural defects on the material properties is more important than the quantum confinement effect, which is confirmed by theoretical calculations and explains the observed anomalies
