Transient behavior of the polarity-reversal current in a nematic liquid-crystal device.
We report on observations of transient behavior of currents induced by the polarity reversal of a dc voltage applied across a nematic liquid-crystal cell. The curve of the time-evolved transient current reveals two peaks for the external voltage larger than a characteristic value. The temperature dependence of drift mobility of ion carriers implies that both the first and second peaks are caused by the director orientation in the bulk.
