The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...
Using novel dot-in-bulk nanocrystals comprising a quantum-confined CdSe core overcoated with a thick, bulk-like CdS shell, we realize a new antibunching mechanism, which allows for simultaneous generation of quantum and classical light from the same nanost ...
The electron spin in a silicon-based quantum dot can be controlled electrically for as long as several tens of microseconds, which improves the prospects for quantum information processing based on this type of quantum dot. ...
Light-emitting devices that utilize thin films of metal nanoclusters as quantum emitters are presented. Implementing Ag as well as Au nanoclusters, the versatility of the approach is demonstrated, and it is shown that the electroluminescence measured from ...
This article presents the dynamics of excitons in a-plane (Al,Ga)N/GaN single quantum wells of various thicknesses grown on bulk GaN substrates. For all quantum well samples, recombination is observed to be predominantly radiative in the low-temperature ra ...
Optical laser fields have been widely used to achieve quantum control over the motional and internal degrees of freedom of atoms and ions(1,2), molecules and atomic gases. A route to controlling the quantum states of macroscopic mechanical oscillators in a ...
We demonstrate a non-classical photon emitter at near infrared wavelength based on a single (In, Ga)As/GaAs epitaxially grown columnar quantum dot. Charged exciton complexes have been identified in magneto-photoluminescence. Photon auto-correlation histogr ...
Semiconductor quantum wires (QWRs) and quantum dots (QDs) are nanoscale heterostructures, which form fascinating low-dimensional systems for fundamental studies of quantum-mechanical effects and are attractive candidates for integration into optoelectronic ...
Three bimodal MRI/optical nanosized contrast agents with high per-nanoparticle relaxivity (up to 2523 mM-1 s-1 at 35 MHz and 932 mM-1 s-1 at 200 MHz) have been prepared connecting up to 115 tris-aqua GdIII complexes to fluorescent non-toxic InP/ZnS quantum ...
Cavity quantum electrodynamics encompasses the study and control of the interactions between quantum light sources and resonant modes of optical cavities. The subject of this thesis is cavity quantum electrodynamics with semiconductor quantum dots (QDs), w ...
