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 ...

Superinjection in Diamond p - i - n Diodes: Bright Single-Photon Electroluminescence of Color Centers Beyond the Doping Limit [PDF]

open access: yesPhysical Review Applied, 2019
Efficient generation of single photons on demand at a high repetition rate is a key to the practical realization of quantum-communication networks and optical quantum computations. Color centers in diamond are considered to be the most promising platform for building such single-photon sources owing to the outstanding emission properties of color ...

Coupled InGaAs Quantum Dots for Electro-Optic Modulation

open access: yesCrystals, 2021
We investigated the growth of vertically coupled In0.75Ga0.25As quantum dots (QDs) by varying the GaAs spacer thickness (d). Vertically-aligned triple-layer QDs of uniform size and highest accumulated strain are formed with d = 5 nm.

Bright Single-Photon Emitting Diodes Based on the Silicon-Vacancy Center in AlN/Diamond Heterostructures

open access: yesNanomaterials, 2020
Practical implementation of many quantum information and sensing technologies relies on the ability to efficiently generate and manipulate single-photon photons under ambient conditions. Color centers in diamond, such as the silicon-vacancy (SiV) center,

Single-molecule Electroluminescence and Beyond [PDF]

open access: yes, 2018
A scanning tunneling microscope (STM) can do more than atomic imaging and manipulation. Its tunneling current can also be used for the excitation of light, converting electron energy to photon energy.
