DOMAIN STRUCTURES OF FERROELECTRIC LEAD TITANATE NANOTUBES FABRICATED AT VARIOUS TEMPERATURES

• Abstract:

  We studied the domain structures of ferroelectric PbTiO₃ nanotubes (NTs) fabricated at various temperatures, using piezoresponse force microscopy (PFM). PTO NTs fabricated at above 500 °C underwent mechanical fracture through development of nanocracks due to grain growth, leading to ferroelectric domains with larger size and lower aspect ratio.
