Abstract: Abstract Lead-free (Na0.5Bi0.5)0.4Sr0.6TiO3-xK0.73Bi0.09NbO3 (abbreviated as NBST-xKBN) ceramics with perovskite structure were prepared by a conventional solid-state reaction method. NBST ceramics modified with KBN content demonstrate strong relaxor behavior. When x = 0.05, the optimal energy storage density… read more here.

DOI: 10.1063/1.4977071
Abstract: This work relates to the integration of the two-layer stack of the proposed multiferroic structure onto silicon substrates. Ba1-xSrxTiO3 is an excellent material for room-temperature voltage-tunable dielectric applications due to its high (e=6000) dielectric constant.… read more here.
