6. Numerical modelling of hot electron transport in Schottky-diodes and heterojunction structures
Sammanfattning : A one-dimensional drift-diffusion model, including energy balance equations, is used to model Schottky-diodes and heterojunction structures. The set of equations are solved simultaneously with a finite-difference iterative scheme. LÄS MER
7. Electronic Structure Calculations: Materials with Weak and Strong Correlations
Sammanfattning : This thesis is devoted to studies of various electronic properties which can be extracted from photoemission spectroscopy. Both weakly and strongly correlated systems are discussed, ranging from free electron metal surfaces to strongly correlated copper oxide compounds. LÄS MER
8. Advanced Metal Oxide Semiconductors for Solar Energy Harvesting and Solar Fuel Production
Sammanfattning : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source which is able to cover the terms sustainability is considered as a favorable alternative. LÄS MER
