Journal ArticleDOI
Light-emitting diodes by band-structure engineering in van der Waals heterostructures
Freddie Withers,O. Del Pozo-Zamudio,Artem Mishchenko,A. P. Rooney,Ali Gholinia,Kenji Watanabe,T. Taniguchi,Sarah J. Haigh,Andre K. Geim,Alexander I. Tartakovskii,Kostya S. Novoselov +10 more
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.

Light-emitting diodes by bandstructure engineering in van der Waals heterostructures
F. Withers,O. Del Pozo-Zamudio,Artem Mishchenko,A. P. Rooney,Ali Gholinia,Kenji Watanabe,T. Taniguchi,Sarah J. Haigh,A. K. Geim,Alexander I. Tartakovskii,K. S. Novoselov +10 more
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.
Journal ArticleDOI
Exciton-polaritons in van der Waals heterostructures embedded in tunable microcavities.
S. Dufferwiel,S. Schwarz,Freddie Withers,Aa A. P. Trichet,Feng Li,M. Sich,O. Del Pozo-Zamudio,C. Clark,Anton Nalitov,Anton Nalitov,Dmitry Solnyshkov,Guillaume Malpuech,K. S. Novoselov,Jm M. Smith,M. S. Skolnick,Dn N. Krizhanovskii,Ai I. Tartakovskii +16 more
TL;DR: The results pave the way for room-temperature polaritonic devices based on multiple-quantum-well van der Waals heterostructures, where polariton condensation and electrical polariton injection through the incorporation of graphene contacts may be realized.
Journal ArticleDOI
WSe2 Light-Emitting Tunneling Transistors with Enhanced Brightness at Room Temperature
Freddie Withers,O. Del Pozo-Zamudio,S. Schwarz,S. Dufferwiel,Paul M. Walker,T. Godde,A. P. Rooney,Ali Gholinia,Colin R. Woods,Peter Blake,Sarah J. Haigh,Kenji Watanabe,T. Taniguchi,Igor L. Aleiner,Andre K. Geim,Vladimir I. Fal'ko,Alexander I. Tartakovskii,K. S. Novoselov +17 more
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.
Journal ArticleDOI
Optical investigation of the natural electron doping in thin MoS2 films deposited on dielectric substrates.
D. Sercombe,S. Schwarz,O. Del Pozo-Zamudio,Feng Liu,Feng Liu,Benjamin J. Robinson,E. A. Chekhovich,I. I. Tartakovskii,Oleg Kolosov,Alexander I. Tartakovskii +9 more
TL;DR: Micro-photoluminescence (PL) and ultrasonic force microscopy are used to explore the influence of the dielectric environment on optical properties of a few monolayer MoS2 films to observe great sensitivity of optical characteristics of 2D films to surface interactions.
