We report here Fe 3 O 4 quantum dots embedded Fe 3 O 4 @C electrode materials via a facile micelle-colloid template method for pushing forward the Li-ion battery technology. To improve uniform dispers...
Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions.
Single photon sources with single semiconductor quantum dots
single-photon source quantum dot (QD) quantum optics photon correlation
2016/1/23
In this contribution, we briefly recall the basic concepts of quantum optics and properties of semicon-ductor quantum dot (QD) which are necessary to the understanding of the physics of single-photon ...

If you add quantum dots – nanocrystals 10,000 times smaller than the width of a human hair – to a smartphone battery it will charge in 30 seconds, but the effect only lasts for a few recharge cycles.H...
The Influence of As on the Morphologies and Optical Characteristics of GaSb/GaAs Quantum Dots
2011/11/18
The influence of As atoms on the morphologies of GaSb quantum dots (QDs) is investigated. Without any special treatment, GaSb quantum rings (QRs) are observed in the embedded GaSb layer even when the ...
Transient effects in electron transport through quantum dots
quantum dot double quantum dot transient current
2011/5/11
We investigate the transient electron transport through the quantum dot and double quantum dot systems coupled with the time-dependent barriers to infinitely large reservoirs of noninteracting electro...
Optical methods used to optimise semiconductor laser structures with tunnel injection from quantum well to InGaAs/GaAs quantum dots
quantum dots optical properties lasers
2011/5/11
We present the results of optical measurements performed on structures consisting of an InGaAs quantum well (QW), separated by a thin barrier from a layer of self-assembled InGaAs quantum dots (QDs). ...

A Brief Discussion on Energy Considerations for GaAs Parabolic Quantum Dots
Hamiltonian operator GaAs parabolic quantum dot Plasma
2010/12/8
The hamiltonian operator corresponding to a GaAs parabolic quantum dot is formulated by analyzing carefully the terms of this operator. In this formulation, certain plasma aspects are discussed with r...
