Oxygen Partial Pressure during Pulsed Laser Deposition: Deterministic Role on Thermodynamic Stability of Atomic Termination Sequence at SrRuO3/BaTiO3 Interface
Yeong Jae Shin, Lingfei Wang, Yoonkoo Kim +8
With recent trends on miniaturizing oxide-based devices, the need for atomic-scale control of surface/interface structures by pulsed laser deposition (PLD) has increased. In partic…
Overcoming the Fundamental Barrier Thickness Limits of Ferroelectric Tunnel Junctions through BaTiO3/SrTiO3 Composite Barriers
Lingfei Wang, Myung Rae Cho, Yeong Jae Shin +5
Ferroelectric tunnel junctions (FTJs) have attracted increasing research interest as a promising candidate for non-volatile memories. Recently, significant enhancements of tunnelin…
Interface control of ferroelectricity in a SrRuO3/BaTiO3/SrRuO3 capacitor and its critical thickness
Yeong Jae Shin, Yoonkoo Kim, Sung-Jin Kang +12
The atomic-scale synthesis of artificial oxide heterostructures offers new opportunities to create novel states that do not occur in nature. The main challenge related to synthesiz…
Polarity control of carrier injection at ferroelectric/metal interfaces for electrically switchable diode and photovoltaic effects
Daesu Lee, S. H. Baek, T. H. Kim +4
We investigated a switchable ferroelectric diode effect and its physical mechanism in Pt/BiFeO3/SrRuO3 thin-film capacitors. Our results of electrical measurements support that, ne…
Double polarization hysteresis loop induced by the domain pinning by defect dipoles in HoMnO3 epitaxial thin films
Daesu Lee, Heung-Sik Kim, Seung Yup Jang +5
We report on antiferroelectriclike double polarization hysteresis loops in multiferroic HoMnO3 thin films below the ferroelectric Curie temperature. This intriguing phenomenon is a…
Domain Switching Kinetics in Disordered Ferroelectric Thin Films
J. Y. Jo, H. S. Han, J. -G. Yoon +3
We investigated domain kinetics by measuring the polarization switching behaviors of polycrystalline Pb(Zr,Ti)O films, which are widely used in ferroelectric memory devices.…
