Functionalizing defects in advanced semiconductors

The project FUNDAMeNT, led by the LENS research group at UiO under Prof. Bengt Svensson, focused on utilizing defects in semiconductors for advanced functionalities. Key goals included developing single-photon sources to explore quantum phenomena, improving energy efficiency in wide band gap semiconductors for lighting and electronics, and innovating nanotechnology through defect-functionalized nanostructures. The project, emphasizing energy-related applications, collaborated internationally and encompassed activities from material growth to device prototyping. Svensson, a renowned physicist, led a diverse team with extensive experience and publications. The group, recognized for its international leadership, heavily utilized national research infrastructures and maintained strong international ties. Team members brought expertise in various aspects of semiconductor physics, contributing significantly to the field. The application team included Prof. Andrej KuznetsovProf.  Eduard MonakhovProf. Clas PerssonAssoc. Prof. Lasse VinesAssoc. Prof. Øystein PrytzDr. Augustinas Galeckas and two young researchers -  Dr. Klaus Magnus Johansen and Dr. Oleksandr I. Malyi.

Casimir effect and van der Waals forces in multilayer systems

Quantum electrodynamic fluctuation forces, which generalized the idealized force predicted by Casimir in 1948, had moved to an ever more central position in our understanding of mesoscopic forces between surfaces and between molecules and surfaces. Casimir-Lifshitz and Casimir-Polder forces had generalized and transformed the notion of van der Waals forces. Advances in experimental technique and the development of new theoretical tools had enabled this transformation. There remained highly controversial issues to be resolved, such as the nature of thermal corrections, the form of Casimir friction, and whether it was realistic to achieve Casimir repulsion and levitation. The driver, however, was the potential applications of these phenomena to physical systems. There, we wanted to link developments in theory to what was needed in practical situations, such as the interaction of molecular gases with oil shale. The project was carried out and completed at the Department of Energy and Process Engineering, Norwegian University of Science and Technology (NTNU) together with researchers from the Centre for Materials Science and Nanotechnology at the University of Oslo (UiO). Joint subprojects with the co-applicants and collaborators from different countries including:  Prof. Iver Håkon Brevik, Dr. Mathias BoströmProf. Clas Persson, Dr. Kristian BerlandDr. Oleksandr I.
