Laser-induced periodic surface structured electrodes with a 45 % energy saving in electrochemical fuel generation through field localization
Chaudry Sajed Saraj, Subhash C. Singh, Gopal Verma +3
Electrochemical oxidation-reduction of radicals is a green and environmentally friendly approach to generating fuels. These reactions, however, suffer from sluggish kinetics due to…
Optical-Field Driven Charge-Transfer Modulations near Composite Nanostructures
Kwang Jin Lee, Elke Beyreuther, Sohail A. Jalil +4
Optical activation of material properties illustrates the potentials held by tuning light-matter interactions with impacts ranging from basic science to technological applications.…
Annihilation mechanism of excitons in a MoS2 monolayer through direct Förster-type energy transfer and multistep diffusion
Kwang Jin Lee, Wei Xin, Chunlei Guo
Atomically thin MoS2 layer is a direct bandgap semiconductor exhibiting strong electron-hole interaction due to the extreme quantum confinement and reduced screening of Coulomb int…
Third harmonic generation of undoped graphene in Hartree-Fock approximation
J. L. Cheng, J. E. Sipe, Chunlei Guo
We theoretically investigate the effects of Coulomb interaction, at the level of unscreened Hartree-Fock approximation, on third harmonic generation of undoped graphene in an equat…
Memories in the Photoluminescence Intermittency of Single Cesium Lead Bromide Nanocrystals
Lei Hou, Chen Zhao, Xi Yuan +6
Single cesium lead bromide (CsPbBr3) nanocrystals show strong photoluminescence blinking, with on- and off- dwelling times following power-law distributions. We investigate the mem…
Generalized Brewster-angle effect in thin-film optical absorbers and its application for graphene hydrogen sensing
Kandammathe Valiyaveedu Sreekanth, Mohamed ElKabbash, Rohit Medwal +7
Generalized Brewster angle (GBA) is the incidence angle at which polarization by reflection for p- and s-polarized light takes place. Realizing s-polarization Brewster effect requi…
Controlling exciton dynamics in two-dimensional MoS2 on hyperbolic metamaterial-based nanophotonic platform
Kwang Jin Lee, Wei Xin, Chunhao Fann +6
The discovery of two-dimensional transition metal dichalcogenides (2D TMDs) has promised next-generation photonics and optoelectronics applications, particularly in the realm of na…
Nonperturbative model for optical response under intense periodic fields with application to graphene in a strong perpendicular magnetic field
J. L. Cheng, C. Guo
Graphene exhibits extremely strong optical nonlinearity when a strong perpendicular magnetic field is applied, the response current shows strong field dependence even for moderate…
Nonlinear magneto-optic effects in doped graphene and gapped graphene: a perturbative treatment
J. L. Cheng, C. Guo
The nonlinear magneto-optic responses are investigated for gapped graphene and doped graphene in a perpendicular magnetic field. The electronic states are described by Landau level…
