Effects of surface forces and phonon dissipation in a three-terminal nano relay

摘要

We have performed a theoretical analysis of the operational characteristicsof a carbon-nanotube-based three-terminal nanorelay. We show that short rangeand van der Waals forces have a significant impact on the characteristics ofthe relay and introduce design constraints. We also investigate the effects ofdissipation due to phonon excitation in the drain contact, which changes theswitching time scales of the system, decreasing the longest time scale by twoorders of magnitude. We show that the nanorelay can be used as a memory elementand investigate the dynamics and properties of such a device.
