"ultrathin 2D semiconductors strong quantum confinement and reduced dielectric effects... stable excitonic species (neutral excitons, trions, biexcitons, defect-bound excitons)... high binding energy between electron and hole exciton stability and long lifetime, increased probability radiative recombination to form photons...  WS2 emplaced sputtered ZnO film, charges migrate across junction... spectroscopic increase in trion-to-exciton ratio... permanent and stable trions"
