1. Molecular beam epitaxy growth and characterization of GaN, AlN and AlGaN/GaN heterostructures
Sammanfattning : The III-nitride materials, consisting of Al, Ga, In and N, have several physical properties that make them attractive for semiconductor devices in electronic and optic applications. A wide range of direct energy bandgaps (0.7 eV - 6.1 eV) can be obtained. LÄS MER
2. Initial growth of GaN on sapphire and growth of AlGaN on GaN by molecular beam epitaxy
Sammanfattning : .... LÄS MER
3. Quantum transport and spin effects in lateral semiconductor nanostructures and graphene
Sammanfattning : This thesis studies electron spin phenomena in lateral semi-conductor quantum dots/anti-dots and electron conductance in graphene nanoribbons by numerical modelling. In paper I we have investigated spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. LÄS MER
4. Spin splitting in open quantum dots and related systems
Sammanfattning : This thesis addresses electron spin phenomena in semi-conductor quantum dots/anti-dots from a computational perspective. In the first paper (paper I) we have studied spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. LÄS MER
5. Multiple Andreev reflections and nonequilibrium Josephson effect in three-terminal superconducting junctions
