Abstract
Raman scattering of layer-type compound 2H-WS 2 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. We also find several peaks due to the second-order processes.
