Dielectric permittivity relates charge separation to an applied electric field. That is, materials with no ions or electrons (i.e., free charges) may transmit electrical current when a voltage is ...
• Ferroelectric–Nonferroelectric Transition: When the capacitor size is reduced to 3.85 μm, ferroelectricity vanishes and an ultrahigh dielectric permittivity of 1466 emerges, without requiring ...
Three RIKEN researchers have created a liquid whose response to an electric field can be tuned over the largest range of any known material. The fluid could find use in various applications including ...
