Changes in the conductance of a Ag/Ta
2 O
5 /Pt atomic switch under the application of ten consecutive input pulses of V
¼ 0.4 V with W of 20 ms at T
of
2 (a) and 0.2 s (b). The insets schematically illustrate the formation of an atomic contact under consecutive input pulses at respective interval times. Also shown
are the results for T
of 0.2 s, but different V
of 0.45 (c), 0.5 (d), and 0.55 V (e). Copyright 2012, IOP
