Thermally activated charge fluctuations in GaAs double quantum dots [PDF]

open access: yes, 2014
In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

A Rapid, Fluorescence Switch-On Biosensor for Early Diagnosis of Sorghum Mosaic Virus

open access: yesBiosensors, 2022
For the first time, a nanobiosensor was established for Sorghum mosaic virus (SrMV) detection. The biosensor consists of cadmium telluride quantum dots (CdTe QDs) conjugated to the specific antibody (Ab) against SrMV coat protein (CP) and carbon quantum ...

Fe doped CdTeS magnetic quantum dots for bioimaging [PDF]

open access: yesJournal of Materials Chemistry B, 2013
A facile synthesis of 3-6 nm, water dispersible, near-infrared (NIR) emitting, quantum dots (QDs) magnetically doped with Fe is presented. Doping of alloyed CdTeS nanocrystals with Fe was achieved in situ using a simple hydrothermal method. The magnetic quantum dots (MQDs) were capped with NAcetyl-Cysteine (NAC) ligands, containing thiol and carboxylic

Electron-photon interaction in quantum dots : spin and entanglement [PDF]

open access: yes, 2005
The interaction of electrons and photons lies at the heart of quantum physics. The most notable phenomena which are described by quantum physics but which obviously invalidate a classical description of the electromagnetic field - the photoelectric ...

Shallow Donor Impurity States with Excitonic Contribution in GaAs/AlGaAs and CdTe/CdSe Truncated Conical Quantum Dots under Applied Magnetic Field

open access: yesNanomaterials, 2021
Using the effective mass approximation in a parabolic two-band model, we studied the effects of the geometrical parameters, on the electron and hole states, in two truncated conical quantum dots: (i) GaAs-(Ga,Al)As in the presence of a shallow donor ...

Multiplexed bio-imaging using cadmium telluride quantum dots synthesized by mathematically derived process parameters in a continuous flow active microreactor

open access: yesMaterials Today Bio, 2021
Quantum dots (QDs) are semiconductor nanocrystals with unique size-tunable emissions. To obtain a precise emission spectrum, monodispersity in size is imperative, which is achieved by controlling the reaction kinetics in a continuous flow of active ...

Probing the interactions of CdTe quantum dots with pseudorabies virus [PDF]

open access: yesScientific Reports, 2015
AbstractQuantum dots (QDs) have become one of the most promising luminescent materials for tracking viral infection in living cells. However, several issues regarding how QDs interact with the virus remain unresolved. Herein, the effects of Glutathione (GSH) capped CdTe QDs on virus were investigated by using pseudorabies virus (PRV) as a model.
