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

open access: yesNature 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.

Tracing the electron transport behavior in quantum-dot light-emitting diodes via single photon counting technique [PDF]

open access: yesNature Communications
The electron injection and transport behavior are of vital importance to the performance of quantum-dot light-emitting diodes. By simultaneously measuring the electroluminescence-photoluminescence of the quantum-dot light-emitting diodes, we identify the

Linearly Polarized Electroluminescence from MoS2 Monolayers Deposited on Metal Nanoparticles: Toward Tunable Room‐Temperature Single‐Photon Sources [PDF]

open access: yesSmall, 2021
AbstractBreak junctions in noble‐metal films can exhibit electroluminescence (EL) through inelastic electron tunneling. The EL spectrum can be tuned by depositing a single‐layer crystal of a transition‐metal dichalcogenide (TMDC) on top. Whereas the emission from the gaps between silver or gold nanoparticles formed in the break junction is spectrally ...

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

open access: yesApplied 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,

Bright Silicon Carbide Single-Photon Emitting Diodes at Low Temperatures: Toward Quantum Photonics Applications

open access: yesNanomaterials, 2021
Color centers in silicon carbide have recently emerged as one of the most promising emitters for bright single-photon emitting diodes (SPEDs). It has been shown that, at room temperature, they can emit more than 109 photons per second under electrical ...

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

open access: yesFrontiers of Optoelectronics, 2022
AbstractThe 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.
