We report field emission from bilayer MoS 2 and monolayer WSe 2 synthesized by CVD on SiO 2/Si substrate. We show that the emitted current follows a Fowler-Nordheim model modified to account for the two-dimensional confinement of charge carriers. We derive the figures of merit of field emission and demonstrate that few-layer transition-metal dichalcogenides are suitable for field emission applications

Abstract
We report field emission from bilayer MoS 2 and monolayer WSe 2 synthesized by CVD on SiO 2/Si substrate. We show that the emitted current follows a Fowler-Nordheim model modified to account for the two-dimensional confinement of charge carriers. We derive the figures of merit of field emission and demonstrate that few-layer transition-metal dichalcogenides are suitable for field emission applicationsFile in questo prodotto:
