Summary: By combining a large-area MoS2 monolayer with silver plasmonic nanostructures in a deformable polydimethylsiloxane substrate, this study investigates the photoluminescence enhancement of MoS2 by surface lattice resonance modes of different silver plasmonic nanostructures. The stable photoluminescence enhancement of MoS2 by silver nanodisc arrays under varying stretching strains is observed, attributed to the mechanical holding effect of the MoS2 monolayer. The results suggest the possibility of stably enhancing the light emission of transition metal dichalcogenides using surface lattice resonance modes in a deformable platform.

Summary: In this study, the coupling between individual asymmetric Au nanocups and excitons in WS2 monolayer and multilayer is investigated. The resonance coupling strength from weak to strong regimes is achieved by adjusting the orientation of the Au nanocups on WS2 monolayer. Different energy detunings are obtained by varying the size of the Au nanocup. A dependence of the coupling strength on the layer number is observed in the coupling between Au nanocups and WS2 multilayer. This research provides a promising approach for realizing different coupling regimes in a simple hybrid system.

Summary: With the rapid development of power semiconductor devices, voltage source inverters (VSIs) have become widely used. The performance of the VSI relies heavily on the modulation strategy, with pulse width modulation (PWM) being the most commonly used method. The existing PWM schemes for VSIs suffer from high total harmonic distortion (THD) and power loss problems. To address this, a hybrid PWM technique is proposed in this paper, which introduces a modified modulating signal and a newly shaped carrier signal. The proposed technique offers lower THD and power losses compared to existing PWM techniques, as demonstrated through simulations and experiments.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
