1. Computational Studies of Metal Clusters and Carbon Nanotubes
Sammanfattning : Carbon nanotubes constitute a promising candidate material in the realisation of nanoscaled electronics. This requires the ability for systematic production of carbon nanotubes with certain properties. This is called selective carbon nanotube growth. LÄS MER
2. In silico studies of carbon nano tubes and metal clusters
Sammanfattning : Carbon nanotubes have been envisioned to become a very important material in various applications. This is due to the unique properties of carbon nanotubes which can be exploited in applications on length scales spanning from the nano world to our macroscopic world. LÄS MER
3. Free Molecular and Metal Clusters Studied by Synchrotron Radiation Based Electron Spectroscopy
Sammanfattning : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. LÄS MER
4. Quantum mechanical models of nanomagnetism in transition metal clusters and diluted magnetic semiconductors
Sammanfattning : This dissertation investigates nanomagnetism in small transition metal clusters and the diluted magnetic semiconductor (Ga,Mn)As. We derive quantum mechanical models aimed at a realistic description of the low energy physics in these systems. LÄS MER
5. The Curious Case of Hot Metal Clusters : Spontaneous decay of excited, small silver and copper cluster anions in DESIREE
Sammanfattning : Clusters anions are complex systems which, when formed with high internal energies, can decay via fragmentation and/or electron loss and may also cool via photon emission (radiative cooling). By studying the spontaneous decay mechanisms of small metal clusters, we can gain insight into the structure and properties of these systems. LÄS MER
