Abstract
A micro electromechanical (mem) device includes a first electrode, a second electrode, and a shaped carbon nanotube with a first end and a second end. The first end of the shaped carbon nanotube is conductively connected to the first electrode and the second end is conductively connected to the second electrode. A system for making the device includes a plurality of electrodes placed outside the growth region of a furnace to produce a controlled, time-varying electric field. A controller for the system is connected to a power supply to deliver controlled voltages to the electrodes to produce the electric field. A mixture of gases is passed through the furnace with the temperature raised to cause chemical vapor deposition (CVD) of carbon on a catalyst. The sequentially time-varying electric field parameterizes a growing nanotube into a predetermined shape.
