Abstract

We use micro-Raman and photoluminescence (PL) spectroscopy at 300 K to investigate the influence of uniaxial tensile strain on the vibrational and optoelectronic properties of monolayer and bilayer MoS${}_{2}$ on a flexible substrate. The initially degenerate ${E}^{\ensuremath{'}}$ monolayer Raman m...
