TL;DR: A detailed theoretical investigation of the atomic and electronic structure of few-layer black phosphorus (BP) is presented to predict its electrical and optical properties, finding that the mobilities are hole-dominated, rather high and highly anisotropic.

TL;DR: A comprehensive joint experiment–theory investigation of point defects in monolayer molybdenum disulphide prepared by mechanical exfoliation, physical and chemical vapour deposition and influence of defects on electronic structure and charge-carrier mobility is predicted by calculation and observed by electric transport measurement.

TL;DR: Platinum disulfide (PtS2), a new member of the group-10 transition-metal dichalcogenides, is studied experimentally and theoretically and can be explained by strongly interlayer interaction from the pz orbital hybridization of S atoms.

TL;DR: This work shows that ultralow-frequency Raman spectroscopy is an ideal tool to uncover the interface coupling of 2d hybrids and heterostructures by directly probing the interlayer interactions in multilayer samples.

TL;DR: In this paper, the vibrational properties of few-layer black phosphorus (FLBP) were investigated and it was shown that these properties are the consequence of strong and highly directional interlayer interactions arising from the electronic hybridization of the lone electron-pairs of FLBP, rather than from van der Waals interactions.
