Single quantum emitters in monolayer semiconductors [PDF]
Nature Nanotechnology, 2015 Single quantum emitters (SQEs) are at the heart of quantum optics and photonic quantum information technologies. To date, all demonstrated solid-state single-photon sources are confined in three-dimensional materials. Here, we report a new class of SQEs based on excitons that are spatially localized by defects in two-dimensional tungsten-diselenide ...

Probing the Optical Dynamics of Quantum Emitters in Hexagonal Boron Nitride
PRX Quantum, 2022 Hexagonal boron nitride is a van der Waals material that hosts visible-wavelength quantum emitters at room temperature. However, experimental identification of the quantum emitters’ electronic structure is lacking, and key details of their charge and ...

Quantum wire intersubband emitter [PDF]
Physical Review B, 2003 A quantum cascade emitter structure is suggested that is based on electronic transitions in an artificial band structure of coupled quantum wires in contrast to the conventional quantum layer systems. The electron transport is normal to the wires in a GaAs/Al_xGa_{1–x}As heterostructure produced by the cleaved-edge overgrowth method.
