Two-dimensional WS₂/MoS₂ heterostructures: properties and applications

Abstract

The successful fabrications of WS2/MoS2 heterostructures provide more sufficient possibilities for optoelectronic and thermoelectric applications than graphene, because of their direct bandgap characteristics; therefore, scientific investigation on WS2/MoS2 heterostructures becomes...

In-plane graphene/boron nitride heterostructures and their potential application as toxic gas sensors

“…32 The heterostructures have drawn attention due to their interesting electric and transport properties aer the successful synthesis by different research groups. [33][34][35][36] These systems are widely used in potential applications including sensing toxic gases due to the high sensitivity and chemical reactivity. [37][38][39] Recently, in 2019, Souza et al investigated the gas sensing properties of graphene/h-BN heterostructure for NO, NO 2 , NH 3 , and CO 2 gas molecules by employing DFT and NEGF theories.…”

Substrate impact on the thickness dependence of vibrational and optical properties of large area MoS2 produced by gold-assisted exfoliation

“…PdSe2), metal monochalcogenides (e.g., GaS), black-phosphorus, black-arsenic, metal trichlorides (RuCl3), and magnetic compounds (Fe3GeTe2) [12]. Hence, it represents a powerful method for the realization of artificial vdW heterostructures [13,14,15] and hybrid 2D/bulk semiconductor devices [16,17,18].…”

The effect of 2D tungsten disulfide nanoparticles on Lewis lung carcinoma cells in vitro

“…Bulk materials WS 2 are semiconductors with an indirect band gap of approximately 1 eV, which becomes a direct bandgap of 1.8-2 eV upon the formation of nanosheets. 7,8 It is accompanied by the appearance of luminescence, which is absent in the bulk material. The maximum luminescence signicantly depends on the size distribution of the layers.…”
