Lifetime analysis of individual-atom contacts and crossover to geometric-shell structures in unstrained silver nanowires

We study the crossover of quantum point contacts from (i) individual-atom contacts to (ii) electronic-shell effects and finally to (iii) geometric-shell effects in electrochemically deposited silver contacts. The method allows the fabrication of mechanically unstrained structures, which is a require...
