Abstract The strong coupling of excitons to optical cavity modes is immense importance when understanding the fundamental physics quantum electrodynamics at nanoscale as well for practical applications in information technologies. There have been several attempts achieving between two-dimensional semiconductors, such transition metal dichalcogenides (TMDCs) and photonic quasi-bound states conti...

A direct band gap nature in semiconducting materials makes them useful for optical devices due to the strong absorption of photons and their luminescence properties. Monolayer transition metal dichalcogenides (TMDCs) have received significant attention as semiconductors a platform applications physics. However, bilayer or thicker layered samples exhibit an indirect gap. Here, we propose method ...

The development of low-resistance source/drain contacts to transition-metal dichalcogenides (TMDCs) is crucial for the realization of high-performance logic components. In particular, efficient hole contacts are required for the fabrication of p-type transistors with MoS2, a model TMDC. Previous studies have shown that the Fermi level of elemental metals is pinned close to the conduction band o...

Transition metal dichalcogenide (TMDCs) monolayers make an excellent component in optoelectronic devices such as photodetectors and phototransistors. Selenide-based TMDCs, specifically molybdenum diselenide (MoSe2) with low defect densities, show much faster photoresponses compared to their sulfide counterpart. However, the typically absorption of atomically thin MoSe2 monolayer high exciton bi...

Two-dimensional (2D) materials, such as graphene and transition metal dichalcogenides (TMDCs), are highly appealing in the fields of electronics, optoelectronics, energy, etc. Graphene, with high conductivity carrier mobility, is an excellent candidate for transparent electrodes. TMDCs have remarkably strong light absorption range visible to infrared wavelength. High-performance photodetectors ...

The controllable preparation of Two-dimensional transition metal chalcogenides (TMDCs) is very important. However, the uncontrollable growth SnS 2 by chemical vapor deposition (CVD) and unsatisfactory performance hydrogen evolution reaction (HER) based on have hindered its applications. Herein, we reported direct synthesis high-quality 1T-SnS with various morphologies via potassium iodide-assis...

Transition metal dichalcogenides (TMDCs), such as MoS2 and WSe2, are free of dangling bonds and therefore make more "ideal" Schottky junctions than bulk semiconductors, which produce Fermi energy pinning and recombination centers at the interface with bulk metals, inhibiting charge transfer. Here, we observe a more than 10× enhancement in the indirect band gap photoluminescence of transition me...

Recently, there has been considerable research interest in two-dimensional (2D) transition-metal dichalcogenides (TMDCs) for future optoelectronic applications. It has been shown that surface passivation with the organic nonoxidizing superacid bis(trifluoromethane)sulfonamide (TFSI) produces MoS2 and WS2 monolayers whose recombination is at the radiative limit, with a photoluminescence (PL) qua...
