Abstract
An atomic scale electroconductivity device with electrostatic regulation is provided that includes a perturbing species having a localized electronic charge ol a dangling bond. A sensing species having an electronic conductivity is placed in proximity to the perturbing species at a distance sufficient to induce a change in the electronic conductivity associated with the localized electronic charge. Electronics are provided to measure the conductivity via the sensing species. The dangling bond functions as a single atom gate electrode.

An electrostatically regulated atomic scale electroconductivity device comprising:
- a perturbing species having a localized electronic charge which is a dangling bond operating as single atom gate electrode;
- a sensing species having an electronic conductivity in proximity to said perturbing species at a distance sufficient to induce a change in the electronic conductivity associated with the localized electronic charge;
- and
- electronics measuring the conductivity through said sensing species as transconductance.
An atomic scale temporally controlled transistor comprising:
- a substrate biased to a substrate voltage with respect to ground;
- a dangling bond extending from a substrate atom and having a charge state from among a charge state group operating as a single atom gate;
- a grounded electrical contact within a localized electronic charge in proximity to the dangling bond;
- a sensing species having an electronic conductivity in proximity to the dangling bond;
- and
- a sensing species contact biased with respect to said substrate, such that the substrate voltage is modified to the charge state of said substrate atom by one electron unit and still within the charge state group.
