Multi-terminal electrical transport measurements of molybdenum disulphide using van der Waals heterostructure device platform
Xu Cui, Gwan-Hyoung Lee, Young Duck Kim +15
Atomically thin two-dimensional (2D) semiconductors such as molybdenum disulphide (MoS2) hold great promise in electrical, optical, and mechanical devices and display novel physica…
High-Speed Electro-Optic Modulator Integrated with Graphene-Boron Nitride Heterostructure and Photonic Crystal Nanocavity
Yuanda Gao, Ren-Jye Shiue, Xuetao Gan +8
Nanoscale and power-efficient electro-optic (EO) modulators are essential components for optical interconnects that are beginning to replace electrical wiring for intra- and inter-…
Tunable Fractional Quantum Hall Phases in Bilayer Graphene
Patrick Maher, Lei Wang, Yuanda Gao +9
Symmetry breaking in a quantum system often leads to complex emergent behavior. In bilayer graphene (BLG), an electric field applied perpendicular to the basal plane breaks the inv…
Measurement of Collective Dynamical Mass of Dirac Fermions in Graphene
Hosang Yoon, Carlos Forsythe, Lei Wang +6
Individual electrons in graphene behave as massless quasiparticles. In surprising twist, it is inferred from plasmonic investigations that collectively excited graphene electrons m…
