1. Charge Transport Simulations for Organic Electronics : A Kinetic Monte Carlo Approach
Sammanfattning : In this thesis we focus on the modelling and simulation of organic electronic devices, investigating their structural and electronic properties. Organic devices have attracted great interest for their innovative properties, but their functioning still represent a theoretical and technological challenge. LÄS MER
2. Variance reduction methods for numerical solution of plasma kinetic diffusion
Sammanfattning : Performing detailed simulations of plasma kinetic diffusion is a challenging task and currently requires the largest computational facilities in the world. The reason for this is that, the physics in a confined heated plasma occur on a broad range of temporal and spatial scales. LÄS MER
3. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments
Sammanfattning : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. LÄS MER
4. Kinetic Monte Carlo Modelling of Organic Photovoltaic Devices
Sammanfattning : Organic photovoltaics (OPVs) is a rapidly growing low-cost PV technology sector that relies on multiple benefits of organic semiconductors viz. being environmental-friendly with a simplified processing/fabrication and tunable properties. LÄS MER
5. Kinetic and Thermodynamic Modeling of Nanowire Growth
Sammanfattning : This thesis aims to expand on the fundamental knowledge of crystal growth, selectively focusing on the area of particle-seeded nanowire growth in the III-V materials system. The growth process is complex. LÄS MER
