Abstract
Methods for production of atomically thin WSe2 films and optical control of their thickness are developed. For two-monolayer-thick WSe2 films, photoluminescence spectra associated with the emission of exciton states of the direct fundamental absorption edge at a temperature of 5–70 K are measured. Along with the emission of intrinsic excitons of the bilayer, new defect-related emission lines are detected.
