Diamond has a tetrahdral shape stucture

  1. May 12, 2005 #1
    Diamond has a tetrahdral shape stucture, an allotrope of carbon with each carbon covalently bonded to 4 others.

    But what happens at the end Carbon of a diamond?

    This "problem" exists, not only for diamond, but all crystals - the surface structure is different from the bulk structure, and is often very strained.

    Notice that by "end carbon", you are refering to the carbon atoms at the surface of single crystal diamond. Surface characterization measurements (notably Auger Spectroscopy) have shown that the diamond surface has a distorted FCC structure - in other words, it's not like the bulk structure, and has wierdness in it.
