Fig. 11: Polarization measurements for Cs2AgIn0.9Bi0.1Cl6.
a Pulse-voltage measurement: Voltage V applied for 2 s followed by 0 V for 100 s and current is monitored during this entire duration. Y-axis shows the ratio of the current measured during the scan to the initial current (immediately right after applying the bias) measured at the corresponding applied voltages. The inset shows the zoomed-in plot of the first 2 s. b Staircase-voltage measurement: a step voltage in multiples of 25 V is applied for 1 s each and current is monitored over the entire time duration. Y-axis (including insets) provides the ratio of maximum current to the measured current over the entire duration. The inset shows the zoomed-in version at 25 and 140 V.
