Transparent and conductive silver nanowires networks printed by laser-induced forward transfer

Networks of silver nanowires (Ag-NWs) can be electrically conductive and optically transparent at the same time. Thus, Ag-NWs are promising candidates for substituting transparent and conductive oxides like indium-tin-oxide. Direct-write methods for printing patterns are suitable in order to reduce...
