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 $\mathrm{\Delta }E\mathrm{\Delta }t$ uncertainty-principle-like limit to the injection of hot carriers from zero-point fluctuations.

卡西米尔腔引起的电导变化

当金属绝缘体-金属器件与卡西米尔型腔连接时，它们的差分电导会增加。较薄的腔体会抑制更多的量子真空模式，从而增加了从绝缘子两侧注入热载流子的不平衡。结果是观察到电导增加。随绝缘体厚度和其他设备参数而变化的其他电导率与不平衡引起的热载流子注入一致。除了电导率变化之外，我们还观察到电流和电压的异常偏移。我们将电导率变化解释为$\mathrm{\Delta }E\mathrm{\Delta }Ť$ 从零点起伏注入热载流子的不确定性原理样极限。
