Ultrafast Charge Transfer in Atomically Thin MoS2/WS2 Heterostructures
Xiaoping Hong, Jonghwan Kim, Su-Fei Shi +7
Van der Waals heterostructures have recently emerged as a new class of materials, where quantum coupling between stacked atomically thin two-dimensional (2D) layers, including grap…
Ultrafast Generation of Pseudo-magnetic Field for Valley Excitons in WSe2 Monolayers
Jonghwan Kim, Xiaoping Hong, Chenhao Jin +5
A new degree of freedom, the valley pseudospin, emerges in atomically thin two-dimensional transition metal dichalcogenides (MX2) and has attracted great scientific interest. The c…
Observation of giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor
Miguel M. Ugeda, Aaron J. Bradley, Su-Fei Shi +9
Two-dimensional (2D) transition metal dichalcogenides (TMDs) exhibit novel electrical and optical properties and are emerging as a new platform for exploring 2D semiconductor physi…
