1. Stacking Faults in Silicon Carbide
Abstract : This PhD thesis comprises a series of theoretical studies on various stacking faults in silicon carbide polytypes, based on first-principles density functional modelling, which lead to a detailed insight into general electronic properties of stacking disordered system. This work is largely motivated by the discovery in 1999 by ABB Corporate Research of the electronic degradation phenomenon in 4H-SiC p-i-n diodes. READ MORE

3. Synthesis–Structure–Property Relationships in Li- and Mn-rich Layered Oxides
Abstract : The commercialisation of Li-ion batteries over the last decade has provided additional impetus for the improvement of existing energy storage technologies. Towards this, a major portion of the global efforts includes exploratory research aimed at the development of new material chemistries. READ MORE

4. Stacking faults, deformation-induced martensite and micromechanics of metastable austenite in steels studied by high-energy synchrotron X-ray diffraction
Abstract : Austenitic stainless steels are known for their remarkable corrosion resistance and exhibit a very high ductility and toughness. They posses the face centered cubic crystal structure. READ MORE

5. First-principles description of planar faults in metals and alloys
Abstract : Phase interface and stacking fault are two common planar defects in metallic materials. In the present thesis, the interfacial energy and the generalized stacking fault energy of random alloys are investigated using density functional theory formulated within the exact muffin-tin orbitals (EMTO) method in combination with the coherent-potential approximation (CPA).
