电荷有序有机盐 θ-(BEDT-TTF)2CsZn(SCN)4 在低温下表现出巨大的非线性传导。这种化合物的电压-电流特性与晶闸管器件相似，因此我们将其命名为有机晶闸管。这种材料在直流电压存在下表现出电流振荡，其产生机制不同于传统振荡电路，因为振荡出现在不显示负导数电阻的样品中。我们进行了标准的电路分析，发现电压-电流曲线在高电流区域“模糊”，并且在模糊区域发生振荡。这种类型的振荡从未被报道过，并且提出了其可能的起源。
The charge ordered organic salt θ-(BEDT-TTF)2CsZn(SCN)4 exhibits a giant nonlinear conduction at low temperatures. The voltage-current characteristics of this compound are similar to those of a thyristor device, after which we named it the organic thyristor. This material shows current oscillation in the presense of dc voltage, which arises from a mechanism different from conventional oscillating circuits, because the oscillation appears in a sample that does not show negative derivative resistance. We have performed a standard circuit analysis, and show that the voltage-current curve is “blurred” in the high current region, and the oscillation occurs in the blurred region. This type of oscillation has never been reported, and a possible origin for this is suggested.
