Single-photon electroluminescence for on-chip quantum networks [PDF]

Applied Physics Letters, 2016
An electrically driven single-photon source has been monolithically integrated with nano-photonic circuitry. Electroluminescent emission from a single InAs/GaAs quantum dot (QD) is channelled through a suspended nanobeam waveguide. The emission line has a linewidth of below 6 μeV, demonstrating the ability to have a high coherence, electrically driven,

Improved transient electroluminescence technique based on time-correlated single-photon counting technology to evaluate organic mobility

Frontiers of Optoelectronics, 2022
Abstract The transient electroluminescence (EL) technique is widely used to evaluate the carrier mobility in the field of organic light emitting diodes. The traditional analog detection strategy using oscilloscopes is generally limited since the background noise causes an underestimation of the mobility value.

Electroluminescence from Localized Defects in Zinc Oxide: Toward Electrically Driven Single Photon Sources at Room Temperature [PDF]

ACS Applied Materials & Interfaces, 2015
Single photon sources are required for a wide range of applications in quantum information science, quantum cryptography, and quantum communications. However, the majority of room temperature emitters to date are only excited optically, which limits their proper integration into scalable devices.

Strong high-energy exciton electroluminescence from the light holes of polytypic quantum dots [PDF]

Nature Communications
High-energy exciton emission could allow single-component multi-colour display or white light-emitting diodes. However, the thermal relaxation of high-energy excitons is much faster than the photon emission of them, making them non-emissive.
