Abstract:
The results of the study of phase transitions of KNO3 encapsulated in carbon nanotubes are presented. It is shown that the temperature range of existence of KNO3 particle ferroelectric phase in nanotubes narrows, similarly to that in ferroelectric semiconductors. The results obtained suggest that external screening by the conductive matrix acts similarly to spontaneous polarization screening in conducting ferroelectrics.
