Abstract
Strained mono- and multilayer MoS₂ structures were synthesized via exfoliation onto thin gold films followed by annealing at 400 °C. Annealing transformed the gold film into nanoparticles, leading to suspended MoS₂ regions. Raman spectroscopy revealed enhanced local strain in suspended monolayer regions compared to those supported by the SiO₂ substrate. Tunneling atomic force microscopy (TUNA) measurements showed that the conductance in monolayers is modulated by both strain and charge transfer from gold nanoparticles. In contrast, the conductance of multilayer MoS₂ showed variations primarily reflecting the effects of strain, indicating local strain-induced narrowing of the bandgap.
