TL;DR: It is found that the exciton dynamics is governed by microscopic disorder on top of the ideal crystal properties, which provides stable monolayer samples with low disorder, avoiding surface contaminations and the resulting exciton broadening and modifications of the dynamics.

TL;DR: In this paper, a systematic study of atomically thin transition-metal dicalcogenides (TMDCs) in its low temperature quantum electronic transport properties is presented, which reveals the correlation between the unusual magnetotransport and disorder in few-layered WTe$2}$, which is indispensable in providing guidance on its future devices application.

TL;DR: In this article, the authors show that due to an enhanced interaction cross section with electrons in a type-I van der Waals heterostructure, made of single-layer molybdenum disulfide and thin boron nitride, cathodoluminescence is strongly enhanced.

TL;DR: In this paper, the coherent nonlinear response of excitons in a single-layer of molybdenum disulphide embedded in hexagonal boron nitride, forming a $h$-BN/MoS$_2$/$h$ -BN heterostructure was measured using four-wave mixing microscopy and imaging.
