The Polarization Properties of the Reflection Spectra of Single-Layer MoS2 and ReS2 on SiO2/Si and Quartz Substrates

Abstract

MoS 2 and ReS 2 are typical transition metal chalcogenides with many excellent electrical and optical properties. Due to different lattice symmetries, ReS 2 offers one more dimension than MoS 2 to tune its physical properties. In this paper, we studied the polarized reflection spectra in single-layer MoS 2 and ReS 2 . The explicit difference identifies strong angle-dependent properties in single-layer ReS 2 distinct from single-layer MoS 2 . The results of samples on both SiO 2 /Si substrate and quartz substrate show single-layer ReS 2 is in-plane anisotropic and the change period of reflection intensity is estimated with the polarization angles.

However, the results of the polarization-resolved PL spectra for each exciton in the MoS 2 /AuNP hybrid structure demonstrate anisotropy of the optical response as a function of the incident orientation.…”
