TL;DR: In this paper, the authors describe light-emitting diodes (LEDs) made by stacking metallic graphene, insulating hexagonal boron nitride and various semiconducting monolayers into complex but carefully designed sequences.

TL;DR: It is shown that light-emitting diodes made by stacking metallic graphene, insulating hexagonal boron nitride and various semiconducting monolayers into complex but carefully designed sequences can also provide the basis for flexible and semi-transparent electronics.

TL;DR: This work reports the fabrication of narrow and smooth capillaries through van der Waals assembly, with atomically flat sheets at the top and bottom separated by spacers made of two-dimensional crystals with a precisely controlled number of layers, using graphene and its multilayers as archetypalTwo-dimensional materials to demonstrate this technology.

TL;DR: A remedial approach based on cleavage, transfer, alignment, and encapsulation of air-sensitive crystals, all inside a controlled inert atmosphere, which offers a venue to significantly expand the range of experimentally accessible two-dimensional crystals and their heterostructures.

TL;DR: It is shown that the EQE of WSe2 devices grows with temperature, with room temperature EQE reaching 5%, which is 250× more than the previous best performance of MoS2 and MoSe2 quantum wells in ambient conditions.
