21. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications
Sammanfattning : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. LÄS MER
22. Optical Studies of InAs Quantum Dots in III-V Semiconductors
Sammanfattning : I this thesis, optical studies of InAs quantum dots (QDs) in GaAs and InP are presented. The electronic structure of these zero dimensional structures, grown in the Stranski-Krastanow growth mode, was studied by photoluminescence spectroscopy (PL), junction space-charge techniques (JSCT) and photoconductivity (PC) measurements.

23. Optical characterization of dilute nitride semiconductors and related quantum structures
Sammanfattning : Dilute nitrides (i.e. LÄS MER
24. Impact of carrier localization on recombination in InGaN quantum wells with nonbasal crystallographic orientations
Sammanfattning : The modern InGaN technology demonstrates high efficiencies only in the blue spectral region and low current operation modes. The growth of InGaN quantum wells (QWs) on nonbasal crystallographic planes (NBP) has potential to deliver high-power blue and green light emitting diodes and lasers. LÄS MER
25. Optical Characterization of GaN/AIGaN Quantum Well Structures
Sammanfattning : The III-nitride material family is particularly well suited for optoelectronic applications, e.g. as UV light emitters in future lighting solutions that are expected to replace the incandescent and fluorescent lamps in use today. LÄS MER
