Abstract

Embodiments of the disclosure are directed to a device for molecule sensing. In some embodiments, the device includes a first electrode separated from a second electrode by a dielectric layer. The first electrode comprises a large area electrode and the second electrode comprises a small area electrode. At least one opening (e.g., trench) cut or otherwise created into the dielectric layer exposes a tunnel junction therebetween whereby target molecules in solution can bind across the tunnel junction.
