Optical polarization in mono and bilayer MoS 2

Abstract:

Optical anisotropy in monolayer- and bilayer-MoS 2 was investigated by polarization resolved photoluminescence measurements. The photoluminescence of monolayer-MoS 2 is found to be partially polarized at 4.2 K and maintains this polarization characteristic up to room temperature, while the photoluminescence of bilayer-MoS 2 shows no obvious polarization. This polarization anisotropy is due to strain effects at the interface between the MoS 2 layer and the SiO 2 substrate, causing symmetr...
