A diamond-based structure includes a substrate, an adhesive material on a face of the substrate, and an array of spaced apart diamond mesas bonded to the substrate by the adhesive material. In particular, each of the diamond mesas can have a growth surface adjacent the substrate and an interfacial surface opposite the substrate, and the interfacial surface can be smooth relative to the growth surface. This structure can be fabricated by providing a sacrificial substrate, forming a plurality of diamond mesas on a face of the sacrificial substrate, bonding the diamond mesas to a transfer substrate, and removing the sacrificial substrate. Accordingly, the interfacial surfaces of the diamond, which are formed adjacent the sacrificial substrate and then exposed by removing the substrate are smooth.

A plasma system is disclosed comprising a vessel suitable for containing a plasma at a pressure of at least about 100 mtorr, a plasma gas in the vessel at a pressure of at least 100 mtorr, an antenna with a substantially planar face positioned adjacent a portion of the vessel for applying an electromagnetic field to the plasma gas to thereby generate and maintain a plasma, and means for applying an external magnetic field to the plasma gas other than the field generated by the antenna, and having a component in a direction substantially perpendicular to the planar face of the antenna.
