The response of electric field has been investigated for the molecular conductorυ-(meso-DMeET) 2PF6, which is in the peculiar electronic state of both checkerboard-type charge ordering and dimer-Mott at low temperatures. The titled crystal shows the large nonlinear conduction and the electric-field induced metastable state. This response is quick in proportional to(electric field)^3. The measurement of raman spectroscopy synchronized to the pulsed electric field suggests the melting of the charge ordering in the metastable state with the intermediate resistivity.

研究了分子导体υ-(meso-DMeET)2PF6的电场响应，该分子导体在低温下处于棋盘型电荷有序和二聚体-莫特的特殊电子态。标题晶体显示出大的非线性传导和电场引起的亚稳态。该响应速度与（电场）^3 成正比。与脉冲电场同步的拉曼光谱测量表明，具有中间电阻率的亚稳态中的电荷有序化。
