Abstract

An organic ferroelectric photoconductor, 2-[(S)-4-(6-methylheptyloxy)phenyl]-6-decylnaphthalene, was prepared and its photoconductive and ferroelectric behaviors were characterized by steady-state and transient electrical measurements. This material exhibited fast carrier transport with an ambipolar mobility of 2.6×10−4 cm2/V s, independent of temperature and electric field. Under a polarized microscope, a fast switching with memory effect was observed visually and the spontaneous polarization was evaluated to be 0.6 nC/cm2 in chiral smectic C phase.
