Abstract

The hybrid diamond-graphite nanowires with lengths up to a few hundred nanometers have been identified as structural units in UNCD films synthesized by chemical vapor deposition with nitrogen gas added. This hybrid material consist of a single crystalline diamond core of 5–6 nm in diameter oriented along the [110] principal axis and graphitic shells of different thickness covering the core.
