Description Glassy carbon has been synthesized for the first time by a simple pyrolysis experiment. The glassy carbon from camphor has been characterized by XRD, Raman, FTIR, ESR and SEM/AFM techniques. It has been found that the undoped glassy carbon film has a resistance of less than about 1 Omega and has n-type character. However, when it was doped with boron by a conventional vapour growth process, its resistance increased to the range 3.5 Omega-14.5 k Omega, depending upon the concentration of boron incorporated, and the resulting material has p-type character, hence showing a semiconducting behaviour unlike the undoped film which has metallic character.
