摘要：

We have observed an increase of the dielectric constant under a bias electric field in the SmC(A)* and SmC(alpha)* phases in 4-(1-methylheptyloxycarbonyl) phenyl 4'-octylcarbonyloxybiphenyl-4-carboxylate. This implies a field-induced phase transition to the ferrielectric and/or to the ferroelectric phases. The transitions were also clearly observed in the field-induced apparent tilt angles in these phases. The electric-field-induced Devil's staircase was confirmed in the SmC(alpha)* phase. Using these observations, a T(temperature)-E(electric field) phase diagram was drawn.
