Chemical Structure, Photo Physics and Emission Control of Single-Photon Emitters in Two-Dimensional Materials

Project description

Quantum technologies go thin

Single-photon sources are fundamental building blocks for ultra-secure communications, super-fast computing and enhanced optical measurement techniques. Single-photon generation has been achieved most notably with semiconductor quantum dots, atomic defects such as nitrogen–vacancy centres in diamond, and carbon nanotubes. Surprisingly, single-photon emission from unusual defect states was also found in several atomically thin 2D semiconductors called transition metal dichalcogenides and hexagonal boron nitride monolayers. Scientists demonstrated that these defects can be prepared at desired locations at will, opening a new class of materials with a potential for quantum technologies. However, engineering quantum emission in 2D materials is still in a very early stage. The mechanism responsible for this phenomenon is the focus of the EU-funded 2D-QuEST project.
