Abstract: A resistance-switchable material containing: an insulating support; and a complementary resistance switchable filler dispersed in the insulating support, wherein the complementary resistance switchable filler has a spherical core-shell structure containing: a spherical conductive core containing a conductive material; and an insulating shell formed on the surface of the core and containing an insulating material. The resistance-switchable material is capable of exhibiting complementary resistive switching characteristics with improved reliability and stability as symmetrical uniform filament current paths are formed in respective resistive layers adjacent to two electrodes with the conductive core of the complementary resistance-switchable filler at the center due to the electric field control effect by the spherical complementary resistance-switchable filler
