Abstract

We performed a X-ray diffraction study of the charge-density wave in K0.30Mo03 under electric fields. In this experiment, we observe the change of the CDW wave vector above the threshold electric field ET. The change occurs mainly in the (2a* - c*) direction which is perpendicular to the one-dimensional axis (b - axis). That also depends on the direction of the electric field and its magnitude. The time resolved X-ray diffraction study showed that the characteristic time of this change is of the order of one millisecond and depends on the electric field magnitude. We also measured transport properties of the CDW state in K0.30MoO3. They contain a thermal hysterysis in the ohmic resistance, an electrical hysterysis in the differential resistance and the temperature dependence of ET which is different from that reported already by Dumas et al. On the nonlinear conductivity in K0.30Mo03, there are two types of samples. One is the swithing sample and the other the non-swithing sample.
