The　existence　of　ferroelectricity　in　organic-inorganic　perovskite　thin　films　has　been　under　debate　over　the　past　few　years.　If　proven　to　exist,　its　magnitude　in　comparison　to　other　known　processes　occurring　in　perovskite,　such　as　electronic　and　ionic　conductivities,　will　determine　its　importance　for　their　optoelectronic　properties.　In　a　recent　paper,　our　group　aimed　at　contributing　to　the　understanding　of　this　topic　by　extending　the　range　of　measurements　beyond　what　is　conventionally　carried　out.　In　particular,　we　employed　three　techniques,　namely,　direct　piezoelectric　force　microscopy,　piezoelectric　force　microscopy,　and　electrostatic　force　microscopy,　which　we　applied　to　two　perovskite　materials,　prepared　with　control　of　film　thickness　and　grain　sizes　that　enabled　the　evaluation　of　morphological　differences.　Based　on　our　experimental　data,　we　concluded　that　lead　halide　perovskites　are　ferroelectricity-free.
