RADIATION DAMAGE IN WELL ORIENTED PYROLYTIC GRAPHITES
Journal Article
·
· Proc. Phys. Soc. (London)
Graphite formed by cracking methane under various conditions was exposed to neutron irradiation. Changes in electronic properties were measuredi after radiation damage by neutron doses of the order l0/sup 17/ neutrons/cm2/sup 2/ after mild annealing around 470 deg C, and after strong annealing at 2200 deg C and above. Effects of radiation damage are proportionately greatest in specimens whose properties are initially nearest to those of ideal graphite. Some discrimination can be made between the types of disorder originally present, and the disorder added by irradiation. Changes of thermoelectric power of graphite in the direction of the c axis show latent increases attributed to disorder frozen in until after mild annealing. (auth)
