Study of field- and temperature-induced phase transitions in PbHfO3 thin films

This proposal is part of the study on the series of phase transitions of lead hafnate PbHfO3 ALD-deposited thin films. The main objective is to determine the structure of the polar phase induced by an electric field. A secondary objective will be to infirm or confirm the presence of a potentially antiferroelectric intermediate phase in between the room temperature antiferroelectric and the high temperature phase seen in bulk single crystal PbHfO3.
