摘要：

Scanning tunneling microscopy (STM) has been used to image at atomic resolution the surface of pyrocarbons deposited at 1680-degrees-C and heat-treated at temperatures up to 2800-degrees-C. Information is obtained on the increase of surface order with HTT. Of special interest are the presence, in HTT 2000 samples, of point defects arranged in a (square-root 7 x square-root 7) R 19. 1-degrees superstructure and attributed to an array of interstitial carbon atoms, and the observation of a moire pattern in the HTT 2200 sample, which could be due to the turbostratic nature of the layer stacking.
