1. 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
2. Study of quantum dots on solar energy applications
Sammanfattning : This thesis studies p-i-n GaAs solar cells with self-assembled InAs quantum dots (QDs) inserted. The values of this work lie in three aspects. LÄS MER
3. Design and Fabrication of III-V Semiconductor Devices for Millimetre- and Submillimetre Wave Applications
Sammanfattning : Devices (various types of diodes) have been fabricated in several different III-V semiconductors (AlxGa1-xAs, In1-xGaxAs, and InAs). The III- V compound semiconductors lend themselves well to high frequency applications due to the high electron mobility that can be obtained. LÄS MER
4. 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
