低亚阈值器件的物理解释在其模式平均传输函数的栅极相关的变化，除了在其整体模式谱的电容性移位。因此，我们探索了各种亚热开关，改变带宽，带隙或振幅的传输，及其组合。电流的朗道理论提供了一种方便的方法来推导亚阈值摆幅在每种情况下分析，并建议如何击败玻尔兹曼限制。
The physics of low subthreshold devices is interpreted in terms of a gate-dependent change in their mode-averaged transmission function, in addition to a capacitive shift in their overall mode spectrum. Accordingly, we explore a variety of subthermal switches that alter the bandwidth, bandgap or amplitude of the transmission, and combinations thereof. The Landauer theory for current flow provides a convenient way to derive the subthreshold swing in each case analytically and suggests ways to beat the Boltzmann limit.
