摘要：

We investigated the response of K0.3MoO3 to high dc electric field in a large temperature range 14-95 K. The remarkable switching from insulating to highly conducting state was observed at 14-75 K. The second threshold field for the switching takes a minimum value at around 50 K. In the highly conducting state, the conductance displays a novel linear correlation to the applied electric field. We also compared the I-E characteristic obtained in the constant-voltage condition and the constant-current condition, which show distinct differential resistances.
