In-plane anisotropy of the optical and electrical properties of layered ReS₂crystals

Abstract

In-plane anisotropic optical and electrical properties of layered ReS2 crystals are reported. The optical anisotropic effects for E || b polarization and E b polarization were studied through polarization-dependent piezoreflectance and optical absorption measurements. The resistivity perpendicular to the b-axis was shown to be several times larger than that along the b-axis.
