| 520 | _ | _ | |a We demonstrate the presence of a hysteresis in tunneling spectra acquired at 4.3 K on cleaved MA-Br terminated (001) surfaces of MAPbBr3 single crystals. Simulations of the tunneling spectra reveal an underlying polarization-voltage (P-V) hysteresis, which is caused by an interplay of subsurface field-induced rotation and alignment of the MA molecules, stabilized by dipole-dipole interactions, and an ion-lattice relaxation. The resulting subsurface polarization is counteracted by a compensating surface polarization, detectable by surface-sensitive tunneling spectroscopy. |
