Effects of post-transfer annealing and substrate interactions on the photoluminescence of 2D/3D monolayer WS2/Ge heterostructures
Abstract
Post-transfer annealing affects optical properties of monolayer WS2/Ge(100) 2D/3D heterostructures. Stronger van der Waals interactions change the electronic band structure of WS2, narrowing its gap and largely quenching the photoluminescence.
