Abstract

The I-V characteristics and grain boundary structures of Pr and Co doped boundaries were investigated using ZnO bicrystals. As such, transmission electron microscopy (TEM) observations and TEM-EDS analysis revealed that atomically joined boundaries were predominantly fabricated and Pr₆O₁₁ existed partially at all the boundaries. Although existence of Pr₆O₁₁ indicates that Pr was saturated at all boundaries, no Pr was detected on the Σ1 boundary.
