Rockford Diamond Technology.

Abstract

Diamond growth in our microwave lamp has been successfully demonstrated. The samples grown for six hours show the crystalline structure with the grain sizes of 1 approx. 3 micrometers by an optical micro- scope. X-ray diffraction (XRD) also indicated these samples were diamond films with random orientation. However, bad samples with black appearance were also obtained sometime. By the Raman measurements, the black films were basically graphite. This phenomenon is strange since the growth conditions for the good and the bad samples were similar. It may be resulted from the change of plasma characteristics by adjusting the impedance. The experimental plan to demonstrate the UV enhancement of diamond growth in microwave plasma assisted CVD (MPACVD) is described in detail. jg p.2
