16. Microscopic Mechanisms of the Formation, Relaxation and Recombination of Excitons in Two-Dimensional Semiconductors
Sammanfattning : Monolayers of Transition Metal Dichalcogenides (TMDs) present a giant leap forward towards the realization of semiconductor devices with atomic scale thickness. As a natural consequence of their two-dimensional character TMDs exhibit a reduced dielectric screening, leading to the formation of unusually stable excitons, i.e. LÄS MER
17. Thermoelectric phenomena in low-dimensional semiconductor systems
Sammanfattning : This thesis investigates thermoelectric effects, predominantly in low-dimensional semiconductors. Various novel phenomena are predicted, investigated and discussed. LÄS MER
18. 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
19. Bilayer Light-Emitting Electrochemical Cells for Signage and Lighting Applications
Sammanfattning : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. LÄS MER
20. Three-Dimensional Metal-Semiconductor Heterostructures for Device Applications
Sammanfattning : Fabrication and characterisation of buried metal contacts in compound semiconductors are demonstrated. The contacts have been investigated due to their usage both as gates in transistors and as active or passive elements in novel devices. LÄS MER
