Atomic resolution images of chemical vapor deposited epitaxial (100) films that had been prepared under ultra-high vacuum were obtained by means of scanning tunnelling microscopy. A (2 x 1) dimer surface reconstruction, and amorphous atomic regions, were observed. The (2 x 1) unit cell was found to measure 0.51nm x 0.25nm. The amorphous regions were identified as being amorphous C. A radial structure which was 1.5nm in diameter was observed on a plane that lay at 20 to the (2 x 1) surface.
