The growth of thin silver nanowires bundle using RbAg4I5 crystal grain thin film and the ionic conductivity of the thin film

We present a novel method for preparing thin silver nanowires bundle by superionic conductor RbAg4I5 crystal grain thin film (CGTF). Under the conditions of room temperature, without any template, when a direct current (DC) electric field of 60 V/m was applied to the silver electrodes deposited on both ends of a strip of RbAg4I5 CGTF, the silver ions congregated at the edge of cathode to form silver nanowires ranging from 50 to 100 nm in diameter. The silver ionic conductivity of this RbAg4I5 CGTF under room temperature was also measured. The experiment proved that the main charge carriers in the RbAg4I5 CGTF under room temperature are silver ions.
