概要:

金沢大学理工研究域　電子情報学系<br />Polycrystalline BiFeO3 (BFO), Ti-doped BFO, Mn-doped BFO, and (Mn, Ti)-codoped BFO (BFMT) thin films were fabricated on Pt/ SrTiO3 (100) substrate by pulsed laser deposition. Observed leakage current behavior in … those ion-doped BFO films indicated the dominance of space-charge-limited current in the high electric field region. The leakage current of the BFMT film was much reduced in relation to the other films due to the formation of deep traps. In the BFMT film, well saturated P-E hysteresis curves were observed. Remanent polarization and coercive field for maximum electric field of 2100 kV/cm were 75 μC/ cm2 and 310 kV/cm, respectively. © 2009 American Institute of Physics. 続きを見る
