Abstract

TN-LCDs fabricated by doping metal nanoparticles of such as Pd, Ag, Au, or Ag-Pd composite are shown to exhibit a frequency modulation electro-optic response with short response time of ms or sub-ms order. These devices are called FM-LCDs. The frequency range spreads from 40 Hz to 2 KHz around a dielectric relaxation frequency that increases with increasing the concentration of metal nanoparticles. This behavior is explained by the equivalent circuit model of heterogeneous dielectrics, for the first time, formulated by the present authors. Further, we discuss the origin of the fast response and the value of electrical conductivity of metal nanoparticles.
