Unconventional anomalous Hall effect from antiferromagnetic domain walls of Nd2Ir2O7 thin films
Woo Jin Kim, John H. Gruenewald, Taekoo Oh +11
Ferroic domain walls (DWs) create different symmetries and ordered states compared with those in single-domain bulk materials. In particular, the DWs of an antiferromagnet (AFM) wi…
Electronic characteristics of ultrathin SrRuO films and their relationship with the metalinsulator transition
Subeen Pang, Yoonkoo Kim, Yeong Jae Shin +4
SrRuO (SRO) films are known to exhibit insulating behavior as their thickness approaches four unit cells. We employ electron energyloss (EEL) spectroscopy to probe the spati…
Electronic Reconstruction Enhanced Tunneling Conductance at Terrace Edges of Ultrathin Oxide Films
Lingfei Wang, Rokyeon Kim, Yoonkoo Kim +10
Quantum mechanical tunneling of electrons across ultrathin insulating oxide barriers has been studied extensively for decades due to its great potential in electronic device applic…
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…
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…
Localized electronic states induced by defects and possible origin of ferroelectricity in strontium titanate thin films
Yong Su Kim, J. Kim, S. J. Moon +6
Several defect configurations including oxygen vacancies have been investigated as possible origins of the reported room-temperature ferroelectricity of strontium titanate (STO) th…
