Dielectric permittivity–voltage hysteresis behavior in deformed helix ferroelectric liquid crystal

Evidence of antiferroelectric-like ordering from the study of dielectric permittivity–voltage behavior in bent core liquid crystalline material showing B2phase

“…Furthermore, Macdonald et al [5] origins following different detected modes in dielectric relaxation spectra of the B 2 liquid crystalline phase are still a source of attraction for physicists. In proper solid state FLCs as well as in surface stabilized ferroelectric liquid crystal (SSFLC), deformed helix ferroelectric liquid crystal (DHFLC) or in AFLC systems, reversal of polarization under external field [6][7][8] results in a hysteretic behavior in the dc biasing field dependence of the capacitance as well as dielectric permittivity (" 0 ), often referred to as the dielectric permittivity-voltage (" 0 -V ) hysteresis. This is a popular method for examining the behavior of FLC materials.…”
