16. Defects and Impurities in CdTe : An ab Initio Study
Sammanfattning : In this thesis defects and impurities in CdTe have been studied with ab initio methods. CdTe is a II-VI semiconductor with many important applications such as γ- and X-ray detectors, solar cells and medical imaging. LÄS MER
17. Magnetic solotronics near the surface of a semiconductor and a topological insulator
Sammanfattning : Technology where a solitary dopant acts as the active component of an opto-electronic device is an emerging field known as solotronics, and bears the promise to revolutionize the way in which information is stored, processed and transmitted. Magnetic doped semiconductors and in particular (Ga, Mn)As, the archetype of dilute magnetic semiconductors, and topological insulators (TIs), a new phase of quantum matter with unconventional characteristics, are two classes of quantum materials that have the potential to advance spin-electronics technology.

18. A Theoretical Perspective on the Chemical Bonding and Structure of Transition Metal Carbides and Multilayers
Sammanfattning : The present thesis deals with a theoretical description of issues regarding chemical bonding, structure and stability of transition metal carbides and multilayered structures. First principles density functional theory has been used extensively to investigate the properties of alloyed solutions of transition metal carbides. LÄS MER
19. Ab initio studies of advanced functional materials with complex magnetism
Sammanfattning : For centuries, magnetism of materials has been an inevitable part of human civilization. Only in the last century, the mysteries of magnetism started to unfold thanks to the development of quantum theory of solids. LÄS MER
