Abstract

Effects of carbon-nanotubes on the transient current induced by a polarity-reversed electric field have been observed in lightly doped nematic liquid-crystal cells at the room temperature. Experimental results indicate that a minute addition of either single-walled or multi-walled carbon nanotubes in the nematic E7 alters the peak current and its time of occurrence for a given applied voltage. It is revealed that the lightly doped cells possess a higher charge mobility in comparison with their pristine counterpart. It is also found that multi-walled carbon nanotubes as a dopant modify the transient-current behavior more substantially than the allotrope single-walled carbon nanotubes do.
