3. 2. Analytical Electron Microscopy Studies for Development of New Carbon Based Materials

   Författare :Staffan Wachtmeister; Stefan Csillag; Gilles Hug; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEM; EELS; CNx thin films; Carbide derived carbons; Gold deconvolution; Resolution improvement; Physics; Fysik; fysik; Physics;

   Sammanfattning : The thesis presents transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) studies of new carbon based materials synthesized with two different techniques. In the first project, nitrogen is incorporated into carbon nanostructures by supersonic cluster beam deposition (SCBD) to favor the formation of curved and cross-linked structures, ultimately aiming at creating a material with high hardness combined with good elasticity.
