PFM phase (a), amplitude (b), and topography (c) images. Electric field-induced polarization switching on the crystalline thin film of R-SEA-Si. PFM phase (d) and (e) amplitude images in the initial state. f PFM phase and (g) amplitude images after applying a tip voltage of + 150 V on the central region and then – 150 V on a smaller central region. Phase and amplitude loops obtained by PFM switching spectroscopy measurements under dark conditions (h) and irradiation of 365 nm (i).
