Adhesion strength of Ag/BaTiO3 interface

The adhesion strength between a silver electrode and pure barium titanate has been determined by using a blister test. The Ag electrode is a porous layer and the barium titanate substrate is dense. The critical interface crack propagation energy Gci of the Ag/BaTiO3 interface ranges between 1.3 J/m2 and 4.2 J/m2.
