Tuning the Optical Signature of Few-Layer M0S2 on Silicon Substrate using Mechanical Nano-Stamping Approach

Not Accessible

Your library or personal account may give you access

Abstract

Spatially modulated biaxial tensile strain in a few-layers M0S2 on pre-patterned Si substrate is demonstrated. Using depth-controlled nanoindentation, localized strain on Si is achieved. Results are verified by observing shifts in the MoS2’s bandgap and phonon modes.
