Raman scattering in layered compound 2H-WS2
- 1. Tsukuba Univ., Sakura, Ibaraki (Japan). Inst. of Physics
Description
Raman scattering of layer-type compound 2H-WS2 has been studied at room temperature. The first-order Raman peaks are observed at 27.4, 357 and 423 cm-1. The low-frequency peak at 27.4 cm-1 is a rigid-layer mode, from which the interlayer shear force constant is estimated. The central force model is applied to the high-frequency phonons. The interlayer shear force constant is much smaller than the intralayer force constants. Several peaks due to the second-order processes are also found. (author)
