WebHere we report observation of a well-defined impurity-induced emission in monolayer WS2 substitutionally doped with rhenium (Re), which is an electron donor. The emission exhibits characteristics of localized states and dominates the spectrum up to 200 K. Gate dependence reveals that neutral impurity centers are responsible for the observed … WebAug 1, 1999 · Thermoluminescence modelling started with very simple models of highly localised point defects, and separation of trapping and recombination centres. Whilst these ideas still dominate the discussions, current research indicates that most defects are far more complex, with localised transitions, and defect interactions extending over many …
