The dynamical properties of longitudinal and transverse conduction of NbSe3 single crystals have been simultaneously studied when the current is applied along the b axis (chain direction). In the vicinity of the threshold electric field for charge-density-wave sliding, the transverse conduction sharply decreases. When a rf field is applied, voltage Shapiro steps for longitudinal transport are observed as usual but also current Shapiro steps in the transverse direction. The possible mechanisms of this effect are discussed.
当电流沿 b 轴（链方向）施加时，我们同时研究了 NbSe3 单晶体的纵向和横向传导的动力学特性。在电荷密度波滑动的阈电场附近，横向传导急剧下降。当施加射频场时，通常会观察到纵向传输的电压 Shapiro 台阶，但也会观察到横向电流 Shapiro 台阶。讨论了这种效应的可能机制。
