Beyond Graphene: Low-Symmetry and Anisotropic 2D Materials

Salvador Barraza-Lopez, Fengnian Xia, Wenjuan Zhu +1

Low-symmetry 2D materials---such as ReS and ReSe monolayers, black phosphorus monolayers, group-IV monochalcogenide monolayers, borophene, among others---have more complex…

Colloquium: Physical properties of group-IV monochalcogenide monolayers

Salvador Barraza-Lopez, Benjamin M. Fregoso, John W. Villanova +2

We survey the state-of-the-art knowledge of ferroelectric and ferroelastic group-IV monochalcogenide monolayers. These semiconductors feature remarkable structural and mechanical p…

Gate-defined, Accumulation-mode Quantum Dots in Monolayer and Bilayer WSe

S. Davari, J. Stacy, A. M. Mercado +7

We report the fabrication and characterization of gate-defined hole quantum dots in monolayer and bilayer WSe. The devices were operated with gates above and below the WSe…

Fluctuation-induced current from freestanding graphene: toward nanoscale energy harvesting

P. M. Thibado, P. Kumar, Surendra Singh +3

At room temperature, micron-sized sheets of freestanding graphene are in constant motion even in the presence of an applied bias voltage. We quantify the out-of-plane movement by c…

Spin-orbit coupling in photonic graphene

Zhaoyang Zhang, Shun Liang, Feng Li +6

We generate experimentally a honeycomb refractive index pattern in an atomic vapor cell using electromagnetically-induced transparency. We study experimentally and theoretically th…
