Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) have emerged as attractive platforms in next-generation nanoelectronics and optoelectronics for reducing device sizes down to a 10 nm scale. To achieve this, the controlled synthesis of wafer-scale single-crystal TMDs with high crystallinity has been continuous pursuit. However, previous efforts epitaxially grow TMD films on insulating substrates (e.g., mica sapphire) failed eliminate evolution antiparallel domains...
In this paper, we propose a switchable bi-functional metamaterial device based on hybrid gold-vanadium dioxide (VO 2 ) nanostructure.

When is metallic state, designed behaves as chiral-selective plasmonic absorber, which result an optical circular dichroism (CD) response with maximum value ∼ 0.7....
When surface plasmon resonance (SPR) occurs, the incident light is absorbed by of SPR structure, thus minimizing intensity reflected light. Therefore, method adopted in this paper to achieve perfect absorption absorbent. In paper, we first propose a multi-frequency broadband absorber structure based on graphene SPR, which uses continuous patterned frequency spectrum form absorption. simulation, sandwich-stack was adopted, whereby situated top SiO2 layer and metal layer. The broad-band bands...
Abstract This study introduces an innovative dual-tunable absorption film with the capability to switch between ultra-wideband and narrowband absorption. By manipulating temperature, can achieve multi-band within 30–45 THz range or spanning 30–130 THz, rate exceeding 0.9. Furthermore, structural parameters of are optimized using particle swarm optimization (PSO) algorithm ensure optimal response. The response is primarily attributed coupling guided-mode resonance local surface plasmon...

By transiting the phase of VO2, functions proposed can be reversibly switched between asymmetric transmission (AT) two different polarization conversions in region. When VO2 operates at isolating state, AT effect achieved with maximum value 0.34 for linearly polarized lights due to excitation enantiomerically...
High-efficiency GaN-based green LEDs are of paramount importance to the development monolithic integration multicolor emitters and full-color high-resolution displays. Here, InGaN quantum well with gradually varying indium (In) content was proposed for improving performance LEDs. The In not only alleviates quantum-confined Stark effect (QCSE), but also yields a low Auger recombination rate. Consequently, gradual exhibited increased light output power (LOP) reduced efficiency droop as...

To achieve this, the controllable growth of wafer-scale TMDs single crystals or periodic single-crystal patterns are fundamental issues. Herein, we present a universal route for synthesizing arrays unidirectionally orientated monolayer ribbons (e.g., MoS2, WS2, MoSe2, WSe2, MoSxSe2-x), by using step edges high-miller-index Au facets...
