Epitaxial growth and the magnetic properties of orthorhombic YTiO3 thin films
S. C. Chae, Y. J. Chang, S. S. A. Seo +3
High-quality YTiO3 thin films were grown on LaAlO3 (110) substrates at low oxygen pressures (<10-8 Torr) using pulsed laser deposition. The in-plane asymmetric atomic arrangements…
Coercive fields in ultrathin BaTiO3 capacitors
J. Y. Jo, Y. S. Kim, T. W. Noh +2
Thickness-dependence of coercive field (EC) was investigated in ultrathin BaTiO3 capacitors with thicknesses (d) between 30 and 5 nm. The EC appears nearly independent of d below 1…
Combinatorial Search for Optimal Hydrogen-Storage Nanomaterials Based on Polymers
Hoonkyung Lee, Woon Ih Choi, Jisoon Ihm
We perform an extensive combinatorial search for optimal nanostructured hydrogen storage materials among various metal-decorated polymers using first-principles density-functional…
Polarization Switching Dynamics Governed by Thermodynamic Nucleation Process in Ultrathin Ferroelectric Films
J. Y. Jo, D. J. Kim, Y. S. Kim +4
A long standing problem of domain switching process - how domains nucleate - is examined in ultrathin ferroelectric films. We demonstrate that the large depolarization fields in ul…
Evidence of metallic clustering in annealed Ga1-xMnxAs from atypical scaling behavior of the anomalous Hall coefficient
H. K. Choi, W. O. Lee, Y. S. OH +9
We report on the anomalous Hall coefficient and longitudinal resistivity scaling relationships on a series of annealed Ga1-xMnxAs epilayers (x~0.055). As-grown samples exhibit scal…
Kinetic stabilization of Fe film on (4 by 2)-GaAs(100)
Jae-Min Lee, S. -J. OH, K. J. Kim +3
We grow Fe film on (4 by 2)-GaAs(100) at low temperature, (~ 130 K) and study their chemical structure by photoelectron spectroscopy using synchrotron radiation. We observe the eff…
