Abstract

The formation of carbon nanoparticles was observed in the gas phase of a magnetron sputtering plasma employing a graphite target, argon gas, and a dc power supply, when the plasma source was operated at a pressure higher than 200 mTorr. Nanoparticles were accumulated in the region just outside of the bright plasma. A part of nanoparticles leaked out from the accumulated region, and was transported toward the downstream side. When the electric potential of the substrate, which was placed in the downstream region, was floating, nanoparticles were trapped by the sheath electron field and were not transported to the substrate. When the substrate was biased at +15 V with respect to the ground potential, nanoparticles were transported efficiently to the substrate
