Abstract

A single nanowire resistive nano-heater (RNH) is fabricated, and it is demonstrated that the RNH can induce highly localized temperature fields, which can trigger highly localized thermo-chemical reactions to grow hierarchical nanowires directly at the desired specific spot such as ZnO nanowire branch growth on a single Ag nanowire.

Keywords: branched heterojunction nanowires; hydrothermal growth; localized temperature fields; nanoscale heaters; single nanowire resistive heater.
