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…
Spontaneous decays of magneto-elastic excitations in noncollinear antiferromagnet (Y,Lu)MnO3
Joosung Oh, Manh Duc Le, Ho-Hyun Nahm +12
When magnons and phonons, the fundamental quasiparticles of the solid, are coupled to one another, they form a new hybrid quasi-particle, leading to novel phenomena and interesting…
Electronic Structures of Oxygen-deficient Ta2O5
Yong Yang, Ho-Hyun Nahm, Osamu Sugino +1
We provide a first-principles description of the crystalline and oxygen-deficient Ta2O5 using refined computational methods and models. By performing calculations on a number of ca…
Instability of Amorphous Oxide Semiconductors via Carrier-Mediated Structural Transition between Disorder and Peroxide State
Ho-Hyun Nahm, Yong-Sung Kim, Dae Hwan Kim
The excited holes occupying the valence band tail states in amorphous oxide semiconductors are found to induce formation of meta-stable O peroxide defects. The valence ban…
