1. Quantum chemical studies of deposition and catalytic surface reactions
Sammanfattning : Quantum chemical calculations have been used to model chemical reactions in epitaxial growth of silicon carbide by chemical vapor deposition (CVD) processes and to study heterogeneous catalytic reactions for methanol synthesis. CVD is a common method to produce high-quality materials and e.g. LÄS MER
2. Towards Controlled Growth and Applications of Carbon Nanotubes
Sammanfattning : This thesis deals with growth, characterization and application of carbon nanotubes. The methods involved in the production of carbon nanotubes are thermal chemical vapor deposition (T-CVD) and plasma enhanced chemical vapor deposition (PE-CVD). LÄS MER
3. Fabrication and characterization of graphene-superconductor devices
Sammanfattning : Graphene is the first single-atom-thick two-dimensional material and exhibits a large set of interesting properties. This thesis consists of two parts. The first regards the growth of large-area graphene using chemical vapor deposition (CVD). LÄS MER
4. Towards graphene-based devices: Fabrication and characterization
Sammanfattning : Graphene is a new material with a large set of impressive properties, interesting both for fundamental studies and applications. Reliable synthesis of large-scale, high-quality graphene is key to its future success. LÄS MER
5. A Theoretical Study: The Connection between Stability of Single-Walled Carbon Nanotubes and Observed Products
Sammanfattning : Over the past 20 years’ researchers have tried to utilize the remarkable properties of single-walled carbon nanotubes (SWCNTs) to create new high-tech materials and devices, such as strong light-weight composites, efficient electrical wires and super-fast transistors. But the mass production of these materials and devices are still hampered by the poor uniformity of the produced SWCNTs. LÄS MER
