Texture-Induced Strain in a WS₂ Single Layer to Monitor Spin-Valley Polarization.

ABSTRACT: Nanoscale-engineered surfaces induce regulated strain in atomic layers of 2D materials that could be useful for unprecedented photonics applications and for storing and processing quantum information. Nevertheless, these strained structures need to be investigated extensively. Here, we present texture-induced strain distribution in single-layer WS₂ (1L-WS₂) transferred over Si/SiO₂ (285 nm) substrate. The detailed nanoscale landscapes and their optical detection are carried out through Atomic Force Microscopy, Scanning Electron Microscopy, and optical spectroscopy. Remarkable differences have been observed in the WS₂ sheet localized in the confined well and at the periphery of the cylindrical geometry of the capped engineered surface. Raman spect
