采用脉冲激光沉积法在Si衬底上制备了富钴ZnCoO纳米颗粒嵌入纤锌矿结构的Zn0.7Co0.3O薄膜。局部超导性的起始温度为5.9 K的混合系统中证明。这种超导电性可能来源于富钴ZnCoO纳米颗粒中的Co ~（3+）或富钴纳米颗粒与Zn0.7Co0.3O基体之间的界面。
Co-rich ZnCoO nanoparticles embedded in wurtzite Zn0.7Co0.3O thin films are grown by pulsed laser deposition on a Si substrate. Local superconductivity with an onset Tc at 5.9 K is demonstrated in the hybrid system. The unexpected superconductivity probably results from Co3+ in the Co-rich ZnCoO nanoparticles or from the interface between the Co-rich nanoparticles and the Zn0.7Co0.3O matrix.
