1. Applications of Ion Beam Methods in Silicide/Si and Silicide/GaAs Nanometre Structures
Sammanfattning : Ion beam methods are used to analyse material (Ion Beam Analysis, IBA) and to modify the target (Ion Beam Modification of Materials, IBMM). In this thesis, ion beams have been used in various IBA techniques to investigate the surface nanometre structures, and also in an ion beam synthesis (IBS) technique to form thin films and to modify material properties.

2. Luminescence of Silicon Nanoparticles Synthesized by Ion Implantation
Sammanfattning : Silicon nanoparticles (SiNPs) have been shown to display luminescence in the visible range with a peak wavelength depending on the nanoparticle size. This finding is of potential interest for integration of optoelectronic devices in semiconductor technology. LÄS MER
