| Abstract: | Dispersed growth techniques are applied to grow carbon nanotubes between metal pads on silicon wafers. Process conditions are tuned to yield nanotube devices having only one multi-walled carbon nanotube connecting the metal pads. The nonlinear transfer characteristics of these devices are often accompanied with high impedance and low conduction current. These attributes can be utilized for a soft limiting circuit with impedance much higher than conventional silicon-based implementations. |
