6. Photoluminescence Studies of Single Quantum Dots
Sammanfattning : This thesis presents photoluminescence (PL) spectroscopy studies of single III-V semiconductor quantum dots (QDs). The electronic properties of the QDs, as well as, the dynamics of the processes taking part inside and in the surroundings of the QDs have been studied by single quantum dot photoluminescence spectroscopy, time resolved spectroscopy, and correlation spectroscopy.

7. Scanning Tunneling Microscopy Induced Luminescence Studies of Semiconductor Nanostructures
Sammanfattning : This thesis treats scanning tunneling luminescence (STL) investigations of semiconductor nanostructures. The STL technique combines scanning tunneling microscopy (STM) with detection of photons, induced by the tunneling electrons. The high spatial resolution in STM and the local excitation allow for optical investigations on the nanometer-scale. LÄS MER
8. 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.

9. Semiconductor Hetero- and Nanostructures
Sammanfattning : In this thesis, chemical beam epitaxy was used to fabricate nm-sized crystalline structures. Most of the systems were based on heterostructures, i.e., combinations of different kinds of crystalline materials. LÄS MER
