単層WS₂のA₁gラマンモードはなぜ安定なのか？
Exploring the stability of the A₁g Raman mode in monolayer WS₂ compared to the more sensitive E₂g mode
Abstract: In monolayer WS₂, the out-of-plane A₁g Raman mode remains remarkably stable under variations in temperature, strain, doping, and moderate defect densities, whereas the in-plane E₂g mode shifts significantly with such perturbations. This article explains A₁g’s vibrational resilience, except under extreme conditions like tungsten vacancies or hi…
