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 ...

Quantum Dots and Applications [PDF]

open access: yesMaterials, 2020
It is the unique size-dependent band gap of quantum dots (QDs) that makes them so special in various applications. They have attracted great interest, especially in optoelectronic fields such as light emitting diodes and photovoltaic cells, because their photoluminescent characteristics can be significantly improved via optimization of the processes by

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 ...
