a Temperature-dependent PL spectra of MoS2/InSe (blue) and MoS2 on SiO2 (scaled by a factor of 0.025) (green). b Temperature dependence of AMoS2 peak energy (points) and FWHM (shaded area) for MoS2/InSe (blue) and MoS2/SiO2 (green). Dotted lines are fits to the O’Donnell-Chen model. c Peak energy difference between MoS2/InSe and MoS2/SiO2 plotted as a function of temperature and with a linear fit (red, dashed line) yielding a slope of −0.22 meV/K. d Quenching of AMoS2 PL intensity measured from MoS2 on InSe compared with MoS2 on SiO2.
