Abstract: Abstract We designed a new type of perovskite-related dielectric energy storage material Na1/3Cd1/3Bi1/3Cu3Ti4O12 with colossal permittivity via an ordinary solid-state method. Remarkably, the Na1/3Cd1/3Bi1/3Cu3Ti4O12 ceramic sintered at 1030 °C displays a decent dielectric performance of colossal… read more here.

Abstract: Crystals of FeSb2 correlated narrow-gap semiconductor host colossal thermopower values. By tuning the impurity level here, we show that electron–phonon scattering that transfers phonon momentum to electrons is efficient only for certain optimal carrier concentration… read more here.
