TL;DR: It is found that the complete lithium intercalation of MoS2 with butyllithium could be effected within 1.5 h with the aid of sonication, and the 2H to 1T phase transition that occurs during the lithiumintercalation could be reversed by IR laser irradiation with a DVD optical drive.

TL;DR: It is now possible to precisely identify few-layered STMD and new high frequency first order A′1 and A1g modes appear, explaining recently reported experimental data for WSe2, MoSe2 and MoS2.

TL;DR: It is confirmed that WTe2 has its minimum energy configuration in a distorted 1T structure (Td structure), which results in metallic-like transport, and the utilization of W Te2 in electronic device architectures such as field effect transistors may need to be reevaluated.

TL;DR: A RRS study of samples of WSe2 with one, two, and three layers, as well as bulk 2H-WSe2, using up to 20 different laser lines covering the visible range shows that Raman enhancement is much stronger for the excited A' and B' states.

TL;DR: A novel strategy for exfoliating crystalline MoS2 into suspensions of nanosheets with retention of the semiconducting 2H phase using substoichiometric amounts n-butyllithium and electron microscopy.
