1. Carbon Nanotube Transistors: Nanotube Growth, Contact Properties and Novel Devices
Abstract : Carbon nanotubes (CNTs) are envisioned to be used as the basic building blocks in future electronics due to their excellent electronic properties such as high mobility, compatibility with high-k dielectrics and small diameters resulting in advantageous electrostatics. This thesis is divided into three separate topics related to increasing the fabrication yield and performance of CNT field effect transistors (CNTFETs). READ MORE

2. Modeling a carbon-nanotube-based nanoelectromechanical relay
Abstract : We have theoretically investigated the properties of a three-terminal carbon-nanotube-based nanoelectromechanical relay. The system operationis based on an coupling between electrical and mechanical degrees of freedom which is a typical characteristic of a NEMS device. READ MORE

3. Field Emission from Multi-walled Carbon Nanotubes and its Application in Nanoelectromechanical Systems
Abstract : Films of aligned multi-walled carbon nanotubes (MWCNTs) areinteresting for applications such as cold emission cathodes in flat-panel display technology and in lighting elements. MWCNTs are, besides this, good candidates to be used innanoelectromechanical systems (NEMS). READ MORE

4. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
Abstract : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. READ MORE

5. Electrochemical characterisations of TiO2 nanotube and lithium-metal electrodes for lithium-based batteries
Abstract : Lithium-ion batteries have since their introduction on the commercial market in the early 1990s played an important role within the field of energy storage. In this thesis both titanium dioxide, TiO2, and lithium metal are investigated based on their properties as anodes for lithium-based battery technologies. TiO2 nanotubes with lengths between 4.
