在四硫富瓦烯 (TTF)-$p$-四氯苯醌晶体中的电传输中观察到显着的非线性和开关效应。实验证据表明这些特征具有与中性离子转变相关的内在起源。讨论了一种可能的机制，即依赖于场的低能激发，例如孤子和中性离子畴壁，它们是TTF-$p$-四氢苯醌晶体中准一维供体-受体堆栈所固有的。
A remarkable nonlinearity and a switching effect have been observed for electric transport in a tetrathiafulvalene (TTF)-$p$-chloranil crystal. Experimental evidence indicates that these features are of an intrinsic origin associated with the neutral-ionic transition. A possible mechanism is discussed in terms of field-dependent low-energy excitations, such as solitons and neutral-ionic domain walls, which are inherent to the quasi-one-dimensional donor-acceptor stacks in the TTF-$p$-chloranil crystal.
