ABSTRACT
A ZnO single-grain-boundary varistor was designed using a bicrystal. Pr and Co dopant cosegregation at the boundary, key to obtain high varistic property, is optimized by controlling grain-boundary misorientation and, hence, grain-boundary atomic structure. Thus obtained single grain boundary exhibited sufficiently high varistic property. The present result opens up the possibility of single-grain-boundary varistors required for future nanoscale electronic devices.

    Varistors are produced from ZnO cylindrically-shaped structures whose quality depends on varying technological conditions at stages of their shape forming and firing. Therefore, the varistors are tested at the final phase of production and faulty elements are excluded. We propose to test the...

    The hole transport through a single grain boundary is investigated in the temperature range from 4 to 300 K using a tetracene bicrystal. The carrier concentration is varied by the field effect. The results can be explained using the grain-boundary-trapping model. A potential barrier is formed at...
