Characterization of integrated heterostructures of SbSI-La0.67Ca0.33MnO3

Heterostructures of ferroelectric antimony sulpho iodide (SbSI) and colossal magnetoresistive La0.67Ca0.33MnO3 (LCMO) were grown on NdGaO3 substrates by pulsed laser deposition (PLD) technique. The integrated structure, with SbSI acting as a gate insulator and LCMO as a semiconductor channel, exhibi...

Description
Summary:Heterostructures of ferroelectric antimony sulpho iodide (SbSI) and colossal magnetoresistive La0.67Ca0.33MnO3 (LCMO) were grown on NdGaO3 substrates by pulsed laser deposition (PLD) technique. The integrated structure, with SbSI acting as a gate insulator and LCMO as a semiconductor channel, exhibited field effect along with a channel modulation of about 10%. This ferroelectric field effect was observed at a voltage of 2 V. The field effect was non-volatile, and very little change was observed in the channel resistance after more than 2 h. Polarisation switching tests showed a small polarisation loss of about 5% after more than 10 exp(7) bipolar switching cycles. 19 refs.
