Electrical conduction at domain walls in lead titanate (PbTiO3) single crystals
The nanoscale electrical conduction behaviour of single crystal lead titanate (PbTiO3) is investigated. Piezoresponse force microscopy measurements show 180° ferroelectric domains on the surface of the mm-sized crystals that are electrically switchable with tip voltages of the order of ∼10 V. Electr...

Zusammenfassung: | The nanoscale electrical conduction behaviour of single crystal lead titanate (PbTiO3) is investigated. Piezoresponse force microscopy measurements show 180° ferroelectric domains on the surface of the mm-sized crystals that are electrically switchable with tip voltages of the order of ∼10 V. Electrical conductivity at domain walls in these crystals was observed using conductive atomic force microscopy. Naturally occurring 180° domains exhibit current flow along the delineating domain wall. The domain wall current flow shows Schottky-like rectifying behaviour. |
