在135 K下，在金属-绝缘体转变点以下的非线性电导区，观察到有机导体α-[双（亚乙基二硫代）四硫富瓦烯] 2 I3的特征电压振荡现象.振荡，这是清晰可见的波形，出现只有当电流施加在电荷交替的方向上的二维条纹电荷秩序。10 kHz量级的频率随所施加的电流线性增加。这些方面的解释从集体运动的二维电荷秩序的观点。
Characteristic voltage oscillation phenomenon is observed in an organic conductor α-[bis(ethylenedithio)tetrathiafulvalene]2I3, in the nonlinear conductivity region below the metal-insulator transition at 135 K. The oscillation, which is clearly visible in the wave form, appears only when the current is applied in the direction of the charge alternation in the two-dimensional stripe charge order. The frequency of order 10 kHz increases linearly with the applied current. These aspects are interpreted from the viewpoint of collective motion of the two-dimensional charge order.
