1. 1. Applications of Ion Beam Methods in Silicide/Si and Silicide/GaAs Nanometre Structures

   Författare :Yanwen Zhang; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phase formation; Nanometre structures; silicide; detection efficiency; Ion Beam Analysis; Ion Beam Synthesis; Time-of-Flight Energy Elastic Recoil Detection ToF-E ERD ; implantation; Fysicumarkivet A:1998:Zhang; Kärnfysik; Nuclear physics; Detla E-E ERD;

   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.
