This opens attractive perspectives to prepare quantum devices based

• Technology (KIT), 76128 Karlsruhe, Germany 10.3762/bjnano.2.81 Abstract 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
