Tungsten ditelluride (WTe2) is a layered transition-metal dichalcogenide
(TMD) with a Td structure, differing from 2H or 1T structure for other TMDs.
Although phonon properties of TMD materials have been studied a lot, research
on Raman fingerprint of WTe2 still remains lacking. Here, we report, for the
first time, the four optical vibrational modes …read more
