초록

The dynamics of nano or micro sized-particles in liquid crystal (LC) medium under an external electric field is of theoretical and technological interest. A fullerene of 10 wt% was doped into the LC medium and its electric field induced motion was controlled by both in-plane and vertical electric fields. In the proposed device, pixel electrode I and pixel electrode II were designed consecutively on the bottom substrate and common electrode on the top of the substrate. When the electric field was applied, the fullerenes start to move in direction of applied electric field. The dark, grey and white states in the proposed device can be obtained by suitable combination of the polarity of applied electric field at pixel electrode I, pixel electrode II and common electrode. The dynamical motions of fullerene particles in LC medium suggest that fullerene can be designed for electronic-paper like displays.
