Ultrafast Graphene Light Emitter
Young Duck Kim, Yuanda Gao, Ren-Jye Shiue +17
Ultrafast electrically driven nanoscale light sources are critical components in nanophotonics. Compound semiconductor-based light sources for the nanophotonic platforms have been…
Temperature Dependent Thermal Boundary Conductance of Monolayer MoS by Raman Thermometry
Eilam Yalon, Özgür Burak Aslan, Kirby K. H. Smithe +9
The electrical and thermal behavior of nanoscale devices based on two-dimensional (2D) materials is often limited by their contacts and interfaces. Here we report the temperature-d…
Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…
Excitons in atomically thin transition metal dichalcogenides
Gang Wang, Alexey Chernikov, Mikhail M. Glazov +4
Atomically thin materials such as graphene and monolayer transition metal dichalcogenides (TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality…
Approaching the Intrinsic Photoluminescence Linewidth in Transition Metal Dichalcogenide Monolayers
Obafunso A. Ajayi, Jenny V. Ardelean, Gabriella D. Shepard +8
Excitonic states in monolayer transition metal dichalcogenides (TMDCs) have been the subject of extensive recent interest. Their intrinsic properties can, however, be obscured due…
Coulomb engineering of the bandgap in 2D semiconductors
Archana Raja, Andrey Chaves, Jaeeun Yu +13
The ability to control the size of the electronic bandgap is an integral part of solid-state technology. Atomically-thin two-dimensional crystals offer a new approach for tuning th…
