Defect and strain engineering of monolayer WSe2 enables site-controlled single-photon emission up to 150 K

Quantum defects in 2D semiconductors are promising quantum light sources, but the required cryogenic temperatures limit their applicability. Here, the authors report a method to create single-photon emitters in monolayer WSe2 operating at temperatures up to 150 K without plasmonic or optical cavitie...

Sumario:Quantum defects in 2D semiconductors are promising quantum light sources, but the required cryogenic temperatures limit their applicability. Here, the authors report a method to create single-photon emitters in monolayer WSe2 operating at temperatures up to 150 K without plasmonic or optical cavities.
