RF Sputtered Nb-Doped MoS₂ Thin Film for Effective Detection of NO₂ Gas Molecules: Theoretical and Experimental Studies.

ABSTRACT: Doping plays a significant role in affecting the physical and chemical properties of two-dimensional (2D) dichalcogenide materials. Controllable doping is one of the major factors in the modification of the electronic and mechanical properties of 2D materials. MoS₂ 2D materials have gained significant attention in gas sensing owing to their high surface-to-volume ratio. However, low response and recovery time hinder their application in practical gas sensors. Herein, we report the enhanced gas response and recovery of Nb-doped MoS₂ gas sensor synthesized through physical vapor deposition (PVD) toward NO₂ at different temperatures. The electronic states of MoS₂ and Nb-doped MOS₂ monolayers grown by PVD were analyzed based on their work
