1. Electronic Structure of intrinsic and doped Silicon Carbide and Silicon
Sammanfattning : Silicon (Si) is the most exploited material within the semiconductor device technology, mainly due to its relatively good electron and hole mobilities and the simplicity to fabricate and process the material. Silicon carbide (SiC) has, however, a wider band gap, a higher breakdown electric field strength, and a higher thermal conductivity, which makes SiC one of the most promising materials for high-power devices.

2. Optical and Electronic Properties of WO3 and Zn Chalcogenides Alloys: A Theoretical study
Sammanfattning : I denna avhandling analyseras optiska och elektroniska egenskaper hos WO3 och Zn-relaterade legeringar med hjälp av täthetsfunktionalteori (DFT). Metoder som går utöver DFT, såsom GW-approximationen och hybridfunktionaler, används för att minimera det fel som genereras av det smala bandgapet som erhålls med konventionella DFT-funktionaler.

4. Memory Effects on Iron Oxide Filled Carbon Nanotubes
Sammanfattning : In this Licentiate Thesis, the properties and effects of iron and iron oxide filled carbon nanotube (Fe-CNT) memories are investigated using experimental characterization and quantum physical theoretical models. Memory devices based on the simple assembly of Fe-CNTs between two metallic contacts are presented as a possible application involving the resistive switching phenomena of this material. LÄS MER
