Bandwidth-Limited Critical Currents in Electrically Tunable Moiré Bands
Riccardo Bertini, Xueqiao Wang, Sergey Slizovskiy +16
Moiré superlattices host narrow minibands whose bandwidth governs correlated and topological phases. Here, we demonstrate that the bandwidth also sets the critical current for the…
Optical detection of charge defects near a graphene transistor using the Stark shift of fluorescent molecules
Carlotta Ciancico, Iacopo Torre, Bernat Terrés +7
Two-dimensional crystals and their heterostructures unlock access to a class of photonic devices, bringing nanophotonics from the nanometer scale down to the atomic level where qua…
Valley-hybridized gate-tunable 1D exciton confinement in MoSe2
Maximilian Heithoff, Álvaro Moreno, Iacopo Torre +14
Controlling excitons at the nanoscale in semiconductor materials represents a formidable challenge in the fields of quantum photonics and optoelectronics. Achieving this control ho…
Engineering 2D material exciton lineshape with graphene/h-BN encapsulation
Steffi Y. Woo, Fuhui Shao, Ashish Arora +20
Control over the optical properties of atomically thin two-dimensional (2D) layers, including those of transition metal dichalcogenides (TMDs), is needed for future optoelectronic…
