Fine structure tuning wse2 electric
Webexternal electric field on the quantum-dot-like emitters hosted by the monolayer flake. The emitters exhibit quantum-confined Stark effect and a modulation in the fine-structure splitting (FSS) as a function of electric field. A maximum modulation of 1500 μeV is observed in the FSS from the studied emitters. Finally, we WebDec 19, 2012 · Geometrical confinement effect in exfoliated sheets of layered materials leads to significant evolution of energy dispersion in mono- to few-layer thickness regime. Molybdenum disulfide (MoS2) was recently found to exhibit indirect-to-direct gap transition when the thickness is reduced to a single monolayer. Emerging photoluminescence (PL) …
