| Abstract Scope |
Electronic structure and optoelectronic properties of a semiconductor are found to be highly sensitive to its overall microstructure and electronic defect states, which in turn depends on the synthesis route as well as process parameters used for its fabrication. It is also equally important to understand the (variation in the) surface defect states and surface electronic structure as these films are always present in a stack, influencing the electrical properties of the next layers and thus the entire device. To this end, several oxide- and sulfide-based semiconducting materials (more specifically, doped ZnO, doped anatase TiO2, Cu2S and SnS) are addressed in this presentation. Moreover, this talk will discuss a systematic interrelation between the defects, electronic structure, and optoelectronic properties of these materials with respect to the (non-equilibrium) synthesis techniques and process parameters, which are important to fabricate optimized device-quality material. |
