Patent ID: 6946693

Claim:
An electron transfer device comprising: (a) a substrate having a horizontal extent; (b) a pillar on the substrate extending from the substrate vertically with respect to the horizontal extent of the substrate, the pillar formed free to vibrate laterally with respect to the vertical length of the pillar and having a resonant frequency, the pillar including an electrical conductor; and (c) drain and source electrodes on the substrate extending from the substrate vertically with respect to the horizontal extent of the substrate, each of the source and drain electrodes having innermost ends thereof which are on opposite sides of the pillar and which are spaced from the pillar, each of the source and drain electrodes including an electrical conductor that is electrically insulated from the electrical conductor of the pillar and the electrical conductor of the other of the source and drain electrodes, the pillar being free to vibrate laterally back and forth between the innermost ends of the drain and source electrodes so as to bring the electrical conductor of the pillar alternately closer to one of the drain and source electrodes and then closer to the other of the drain and source electrodes as the pillar vibrates.
