Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide
Rusen Yan, Qin Zhang, Oleg A. Kirillov +10
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collec…
Efficient terahertz electro-absorption modulation employing graphene plasmonic structures
Berardi Sensale-Rodriguez, Rusen Yan, Mingda Zhu +3
We propose and discuss terahertz electro-absorption modulators based on graphene plasmonic structures. The active device consists of a self-gated pair of graphene layers, which are…
Raman and Photoluminescence Study of Dielectric and Thermal Effects on Atomically Thin MoS2
Rusen Yan, Simone Bertolazzi, Jacopo Brivio +7
Atomically thin two-dimensional molybdenum disulfide (MoS2) sheets have attracted much attention due to their potential for future electronic applications. They not only present th…
A New Class of Electrically Tunable Metamaterial Terahertz Modulators
Rusen Yan, Berardi Sensale-Rodriguez, Lei Liu +2
Switchable metamaterials offer unique solutions for efficiently manipulating electromagnetic waves, particularly for terahertz waves, which has been difficult since naturally occur…
Transistors with Chemically Synthesized Layered Semiconductor WS2 Exhibiting 105 Room Temperature Modulation and Ambipolar Behavior
Wan Sik Hwang, Maja Remskar, Rusen Yan +9
We report the realization of field-effect transistors (FETs) made with chemically- synthesized layered two dimensional (2D) crystal semiconductor WS2. The 2D Schottky-barrier FETs…
