SELF-COMPRESSION OF THE CARBON ONIONS UNDER ELECTRON IRRADIATION

Abstract

      Diamond structures as well as the Iron carbide compound is the special structures, hardly generated in normal conditions, they are formed in the extreme conditions, temperature and pressure is very higher. However, under the effect of high energy electron beam irradiation, Carbon onions structures are formed, they are self-compression constitute Iron carbide structures and Diamond inside core, the process was observed by high resolution transmission electron microscopy (HRTEM).
