Atmospheric pressure glow discharge plasma sintering of solvent-free silver lines made by laser ablation dry aerosol printing

<!-- START_ABSTRACT --> <p> We describe a novel method of using atmospheric pressure glow discharge plasma for sintering printed conducting lines of silver. The solvent-free metal lines were prepared by laser ablation dry aerosol printing on Al2O3 ceramic substrate. The plasma was used in transferred-discharge mode where the silver line acts as the cathode of the discharge, thus ensuring that a substantial fraction of the plasma power is coupled to the silver line. It was observed that plasma power of 6.5 W led to clear densification of the line, and electrical resistivity of (7.6 ± 1.5) × 10−8 Ω m. </p> <!-- END_ABSTRACT --> <!-- START_TEMPLATE --> <ul> <li> Source: </li> <li> Tags: </li> </ul> <!-- END_TEMPLATE -->
