摘要：

In this letter we present an investigation on probing leakage current and ferroelectricity of Pb(Zr, Ti)O-3(PZT)/YBa2Cu3Ox heterostructure using a modified atomic force microscopy. Inhomogeneities of leakage current and ferroelectric properties were concurrently mapped and quantitatively studied on a nanometer scale. It shows that microscopically the leakage current can be described by a model based on space-charge-limited current. (C) 2000 American Institute of Physics. [S0003-6951(00)00914-1].
