Extended Data Fig. 7: Space-charge-limited-current measurement of the epitaxial α-FAPbI3 with different strains.
From: Strain engineering and epitaxial stabilization of halide perovskites
a–d, I–V characteristic curves for the space-charge-limited-current measurement of the epitaxial α-FAPbI3 film with different strains. While the forward scans indicate a typical trap-filling process with increasing the applied voltage, the reverse scan doesn’t show a detrapping process. Number of experiments, n = 5 for each strain value. ntrap, calculated trap density.
