Abstract:

We have investigated the transverse alternating and direct current effect on the charge-density wave (CDW) dynamical properties in K0.3MoO3 by measuring I-V characteristics.The results show that,no matter whether DC or AC transverse current is used,the CDW depinning field (Et) along the longitudinal direction is effectively suppressed as the transverse current increases.But the effect of AC current on I-V characteristics is weaker,and probably closer to the intrinsic effect.A frequency dependence of transverse AC modulation effect was observed.
