Abstract
Chemical state of nitrogen atoms in the carbon films prepared from differen t organic precursors (different polyimides, POD and PAN) was studied by XPS and chemical analysis. In the carbon films prepared from all these precurs ors by the heat-treatment up to 1200 degrees C, nitrogen atoms give a singl e XPS peak at 401 eV, suggesting that nitrogen atoms substitute carbon atom s in hexagonal carbon layers.
