Abstract

Highly oriented pyrolytic graphite was irradiated at room temperature with 300-keV electrons. High resolution transmission electron microscopy and electron energy loss spectroscopy were employed to study the structure of electron-irradiated graphite. All the results obtained here consistently indicated die absence of long-range order periodicity in the basal plane and the loose retention of the c-axis periodicity. The structure was modeled based on a mixture of sixfold and non-sixfold atom rings. The formation of non-sixfold atom rings was related to the observed buckling and discontinuity of the original graphite basal plane.
