论文摘要
我们开发了渗透类型的脉冲传导理论，例如非晶体半导体和纳米金属化合物。对于短电压脉冲，相应的电流与脉冲长成反比，并且由于渗透键的电阻区域中强烈的局部场而表现出明显的非粉状性。这些字段可以触发本地切换事件，以响应脉冲火车而逐渐变化。我们的预测为一类可使用各种材料实现的多价非易失性记忆开放了一个场所。
We develop a theory of pulse conduction in percolation type of materials such as noncrystalline semiconductors and nano-metal compounds. For short voltage pulses, the corresponding electric currents are inversely proportional to the pulse length and exhibit significant nonohmicity due to strong local fields in resistive regions of the percolation bonds. These fields can trigger local switching events incrementally changing bond resistances in response to pulse trains. Our prediction opens a venue to a class of multi-value nonvolatile memory implementable with a variety of materials.
