Abstract
In a general aspect, junction properties of tunnel junctions are altered by voltage-assisted annealing processes. In some cases, a method includes obtaining a circuit comprising a tunnel junction, modifying a junction resistance of the tunnel junction by applying a voltage across the tunnel junction, and obtaining a measured value of the junction resistance. The tunnel junction may include a metal and a metal oxide.
