Physics of intraband quantum dot optoelectronic devices [PDF]

open access: yes, 2007
In last two decades, semiconductor nanostructures, such as quantum wells, wires and dots, have been recognised as sources and detectors of radiation in the mid- and far-infrared region of the spectrum.

Accessing the quantum world through electronic transport in carbon nanotubes [PDF]

open access: yes, 2006
In this thesis we will focus on (a) superconducting electrodes attached to carbon nanotube quantum dots in order to study the effects of superconducting correlations on quantum systems and (b) local gate control of carbon nanotubes in order to define

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 ...

Ultrafast dynamics in InAs quantum dot and GaInNAs quantum well semiconductor heterostructures [PDF]

open access: yes, 2007
The quantum confined Stark effect (QCSE) and ultrafast absorption dynamics near the bandedge have been investigated in p-i-n waveguides comprising quantum confined heterostructures grown on GaAs substrates, for emission at 1.3um.

Piezomagnetic Quantum Dots [PDF]

open access: yesPhysical Review Letters, 2008
We study the influence of deformations on magnetic ordering in quantum dots doped with magnetic impurities. The reduction of symmetry and the associated deformation from circular to elliptical quantum confinement lead to the formation of piezomagnetic quantum dots.

Photovoltaic Performance of a Nanowire/Quantum Dot Hybrid Nanostructure Array Solar Cell

open access: yesNanoscale Research Letters, 2018
An innovative solar cell based on a nanowire/quantum dot hybrid nanostructure array is designed and analyzed. By growing multilayer InAs quantum dots on the sidewalls of GaAs nanowires, not only the absorption spectrum of GaAs nanowires is extended by ...
