Mechanical properties of monolayer GaS and GaSe crystals
(American Physical Society, 2016-12)
The mechanical properties of monolayer GaS and GaSe crystals are investigated in terms of their elastic constants: in-plane stiffness (C), Poisson ratio (ν), and ultimate strength (σU) by means of first-principles calculations. ...
Few-layer MoS2 as nitrogen protective barrier
(IOP Publishing, 2017-09)
We report experimental and theoretical investigations of the observed barrier behavior of few-layer MoS2 against nitrogenation. Owing to its low-strength shearing, low friction coefficient, and high lubricity, MoS2 exhibits ...
Electrically switchable metadevices via graphene
(American Association for the Advancement of Science, 2018-01)
Metamaterials bring subwavelength resonating structures together to overcome the limitations of conventional materials. The realization of active metadevices has been an outstanding challenge that requires electrically ...
Graphene-quantum dot hybrid optoelectronics at visible wavelengths
(American Chemical Society, 2018-06)
With exceptional electronic and gate-tunable optical properties, graphene provides new possibilities for active nanophotonic devices. Requirements of very large carrier density modulation, however, limit the operation of ...
