Medium-range order in pyrolyzed carbon films: Structural evidence related to metal–insulator transition
2002
Journal of Applied Physics
Structural properties of carbon films prepared by the pyrolysis of tetra chloro phthalic anhydride are investigated in an attempt to correlate it with the metal-insulator transition observed earlier as a function of deposition temperature, from electrical transport studies. Anomalous features are observed which evolve as the pyrolysis temperature is varied from 700 to 900°C. This includes prepeaks in the x-ray diffraction pattern in the region less than 1 Å Ϫ1 providing evidence for medium
