Topography of the BSTO-based membrane (a); surface potential signal obtained immediately after pre-polarization (b), after 1 h (c), after 2 h (d), and profiles (e) drawn in the middle of the images presented in (b–d): 1 is immediately after polarization; 2 is 1 h later and 3 is 2 h after polarization (the dark and light squares correspond to polarization voltages of –10 V and +10 V, respectively)
