Temperature Dependence of Optical Properties of MoS<sub>2</sub> and WS<sub>2</sub> Heterostructures Assessed by Spectroscopic Ellipsometry

Temperature Dependence of Optical Properties of MoS<sub>2</sub> and WS<sub>2</sub> Heterostructures Assessed by Spectroscopic Ellipsometry

We report the complex dielectric function <i>ε</i> = <i>ε</i><sub>1</sub> + <i>iε</i><sub>2</sub> of MoS<sub>2</sub>/WS<sub>2</sub> and WS<sub>2</sub>/MoS<sub>2</sub> heterostructures and thei...
