Optimizing Broadband Terahertz Modulation with Hybrid Graphene/Metasurface Structures
S. -F. Shi, B. Zeng, H. -L. Han +6
We demonstrate efficient terahertz (THz) modulation by coupling graphene strongly with a broadband THz metasurface device. This THz metasurface, made of periodic gold slit arrays,…
Adsorption-Induced Solvent-Based Electrostatic Gating of Charge Transport through Molecular Junctions
Michele Kotiuga, Pierre Darancet, Carlos R. Arroyo +2
Recent experiments have shown that transport properties of molecular-scale devices can be reversibly altered by the surrounding solvent. Here, we use a combination of first-princip…
Energy-dependent resonance broadening in symmetric and asymmetric molecular junctions from an ab initio non-equilibrium Green's function approach
Zhenfei Liu, Jeffrey B. Neaton
The electronic structure of organic-inorganic interfaces often feature resonances originating from discrete molecular orbitals coupled to continuum lead states. An example are mole…
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…
Gate-dependent Pseudospin Mixing in Graphene/Boron Nitride Moire Superlattices
Zhiwen Shi, Chenhao Jin, Wei Yang +13
Electrons in graphene are described by relativistic Dirac-Weyl spinors with a two-component pseudospin1-12. The unique pseudospin structure of Dirac electrons leads to emerging phe…
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…
