研究了采用热连接技术制备的ZnO双晶在不同取向差下的（0001）扭转晶界的电流-电压特性。高分辨透射电子显微镜证实，晶界完美连接，没有晶间相。在这项研究中制备的双晶体没有表现出非线性的I-V特性，无论在边界的相干性。因此，晶界原子组态与ZnO（0001）扭曲晶界双肖特基势垒的形成无关。
Current-voltage (I–V) characteristics across (0001) twist boundaries with various misorientation angles were investigated in undoped ZnO bicrystals fabricated by a hot-joining technique. It was confirmed by high-resolution transmission electron microscopy that the boundaries were perfectly joined without intergranular phase. None of the bicrystals prepared in this study exhibited nonlinear I–V characteristics irrespective of coherency at the boundaries. Therefore, grain-boundary atomic configuration had no relation to the formation of double Schottky barriers at the (0001) twist boundaries in ZnO.
