Casimir-cavity-induced conductance changes

The differential conductance of metal-insulator-metal devices increases when they are joined with Casimir cavities. An imbalance in injection of hot charge carriers from each side of the insulator is increased with thinner cavities that suppress more quantum vacuum modes. The result is an observed increase in conductance. Additional conductance changes, with insulator thickness and other device parameters, are consistent with an imbalance-induced injection of hot carriers. In addition to the conductance changes, we observe anomalous offsets in the current and voltage. We interpret the conductance changes in terms of a Delta E Delta t uncertaintyprinciple-like limit to the injection of hot carriers from zero-point fluctuations.

Automated summary

The differential conductance of metal-insulator-metal devices increases when joined with Casimir cavities due to an imbalance in injection of hot charge carriers. Thinner cavities suppress more quantum vacuum modes and result in an observed increase in conductance. Changes in conductance with insulator thickness and other device parameters are consistent with an imbalance-induced injection of hot carriers. Additionally, anomalous offsets in current and voltage are observed, which are interpreted as a limit to the injection of hot carriers from zero-point fluctuations similar to a Delta E Delta t uncertainty principle.
