Patent ID: 8034218

Claim:
A method for growing oriented carbon nanotubes on a sample, using a target of carbon or variety of carbon, comprising: conducting the method in an RF sputtering device comprising a deposition chamber where a plasma predominates, and comprising a cathode, an anode and providing an RF voltage, wherein the cathode has a main face opposite a main face of the anode, the sample and the target are placed between the anode and the cathode, above the anode and in front of the cathode, the sample is arranged in contact with the target in such a way that the target presents a free surface to the cathode, the sample presents to the cathode, a free surface comprising at least partially a catalytic layer, the target is in direct contact with the anode and the sample, the sample is in direct contact with the target, the plasma causes the growth of carbon nanotubes on the catalytic layer, and there is no hot filament in the RF sputtering device.
