TL;DR: The electrical and optical measurements show distinct layer-dependent semiconductor-to-semimetal evolution of 2D layered PtSe2 and the high room-temperature electron mobility and near-infrared photo-response, together with much better air-stability, make Pt Se2 a versatile electronic2D layered material.

TL;DR: In this paper, the most widely studied 2D transition metal dichalcogenides (TMD) are focused on, and an overview of recent progress on doping, contact, and interface engineering of the TMD-based field effect transistors is provided.

TL;DR: Graphene-draping strategy for antiphotocorrosion of semiconductor photocatalysts is environmentally friendly as it prevents them from entering into the surrounding environment, thus eliminating the possible secondary pollution.

TL;DR: In this paper, the authors investigated the layer-dependent negative trion PL of 2D MoS2, and further constructed heterostructures with transition metal dichalcogenides and transition metal oxides (TMOs).

TL;DR: The Raman spectra of the edges feature newly observed forbidden Raman modes, which are originally undetectable from the body region, by selecting the edge type and the polarization directions of the incident and scattered light.
