a Example set pulse and current response with a pulse width of 10 µs. The voltage pulse appears to be shorter because the current-limiting circuit decreases the applied voltage after the set event. The current limit was set to 50 µA. The gray area indicates the set time tset. b Set kinetics plot with extracted set times tset versus the applied voltage pulse amplitude. The trend of the experimental data under ambient conditions can be described by the Butler-Volmer equation (orange line). A decreased Ni ion concentration c reflects vacuum-like conditions, leading to significantly longer switching times (green line).
