TL;DR: Using the energy-state-resolved ultrafast visible/infrared microspectroscopy, unambiguous experimental evidence is obtained of the charge transfer intermediate state with excess energy, during the transition from an intralayer exciton to an interlayer exciton at the interface of a WS2/MoS2 heterostructure.

TL;DR: This work makes use of the lone pair electrons found in most of 2D metal chalcogenides and reports a functionalization method via a Lewis acid-base reaction that does not alter the host structure and fabricate planar p-n junctions on 2D InSe with improved rectification and photovoltaic properties.

TL;DR: In this article, an in situ quantitative tensile testing platform is developed to enable the uniform in-plane loading of a freestanding membrane of 2D materials inside a scanning electron microscope.

TL;DR: A new concept for junction fabrication by connecting multiple regions with varying layer thicknesses, based on the thickness dependence, is demonstrated, which is only possible in super-thin-layered 2D materials.
