DOI: 10.1021/acsnano.0c09162
Abstract: We performed polarized Raman spectroscopy on mechanically exfoliated few-layer MoTe2 samples and observed both 1T' and Td phases at room temperature. Few-layer 1T' and Td MoTe2 exhibited a significant difference especially in interlayer vibration modes,… read more here.

DOI: 10.1038/s41598-018-35510-4
Abstract: We report a study of Raman scattering in few-layer MoTe2 focused on high-frequency out-of-plane vibrational modes near 291 cm−1 which are associated with the bulk-inactive $${{\rm{B}}}_{2{\rm{g}}}^{1}$$B2g1 mode. Our temperature-dependent measurements reveal a double peak structure of… read more here.
