1. Theoretical and optical investigations of some III-V based quantum wells and modulation doped heterostructures
Sammanfattning : This thesis is based on a combination of theoretical calculations and optical studies of the electronic structure and the radiative recombination processes in some III-V based quantum wells and ?-type modulation doped heterostructures. The optical studies includes photoluminescence (PL) spectroscopy, PL excitation (PLE) spectroscopy, and time-resolved PL. LÄS MER
2. Long Term Studies of Insect Abundances in Temporary Wetlands in Relation to Hydrology, Predation and Bti
Sammanfattning : Long-term insect abundances have been studied to investigate factors structuring the insect communities of the temporary wetlands around the River Dalälven floodplain. In the wet meadows and swamps in the River Dalälven floodplains recurrent floods are the ultimate prerequisite for high production of floodwater mosquitoes. LÄS MER
