Copper and Copper Oxide Nanostructures from an Electroless Method
In collaboration with Nadiia Kulyk and Prof. Chan-hwa Chung in the Chemical Engineering Department of SKKU, we are developing a facile technique involving a new copper seed layer to selectively deposit copper via an electroless method on various substrates, including organic transparent PMDS and PI as well as on glass, PCB board, SiO2, etc. Spin coating our precursor onto the substrates, followed by laser annealing or patterning and baking, and finally subsequent reduction at low temperature, leads to catalytically active copper. Thus the nanopatterns yield the selective deposition of copper in a heated electroless solution. These structures can then be oxidized to achieve copper oxide. The technique enables non-electronic low temperature deposition of high quality copper and copper oxide (after heat treatment). We are investigating the electrical properties of the nanolines before and after electroless plating has been tried.
