研究了氢化和氘化非晶硅薄膜（a-Si:H、a-Si:D）的拉曼光谱。与a-Si:H的TO拉曼峰相比，a-Si:D的横向光学(TO)拉曼峰的不对称展宽是由于Si-D摇摆模式和Si-Si TO声子模式之间的耦合而不是结构差异造成的。
The Raman spectra of hydrogenated and deuterated amorphous silicon films (a-Si:H, a-Si:D) have been investigated. It is suggested that the asymmetrical broadening of the transverse-optical (TO) Raman peak of a-Si:D compared to the TO Raman peak of a-Si:H results from the coupling between the Si–D wagging mode and the Si–Si TO phonon mode rather than the structural difference.
