We investigated interlayer phonon modes of mechanically exfoliated few-layer 2H-SnS<sub>2</sub> samples by using room temperature low-frequency micro-Raman spectroscopy. Raman measurements were performed using laser wavelengths of 441.6, 514.4, 532 and 632.8 nm with power below 100 μW and inside a vacuum chamber to avoid photo-oxidation. The intralayer E<sub>g</sub> and A<sub>1g</sub> modes are observed at ~206 cm<sup>-1</sup> and 314 cm<sup>-1</sup>, respectively, but the E<sub>g</sub> mode is ...[more]
