Abstract
Au can be easily formed by thermal calcination via the reduction of chloroauric acid. However, a conventional hot-plate or furnace calcination procedure often results in a piecewise and island-like film. In this study, the rapid synthesis of continuous Au thin films from spin-coated chloroauric acid precursor films is demonstrated by using an atmospheric pressure plasma jet (APPJ). The sheet resistance decreases from 2.175 to 0.997 Ω sq-1 as the APPJ processing time increases from 7 to 60 s. This ultrafast synthesis of continuous Au thin films is made possible by the synergistic effect of the highly energetic/reactive nitrogen species and the heat generated by APPJs.
