摘要：

The Raman spectrum of InSe was taken at room temperature and at liquid nitrogen temperature. We found that the TO (199 cm-1) and LO (212 cm-1) modes, together with their overtones and combinations at 400, 416 and 423 cm-1 disappeared at lower temperatures. We attribute the vanishing of these modes at low temperatures to a change of phase from ε{lunate} to β polytype. © 1979.
