Composition-dependent polarization switching behaviors of (111)-preferred polycrystalline Pb(Zr_{x}Ti_{1-x})O_{3} thin films
J. Y. Jo, S. M. Yang, H. S. Han +8
We investigated the time-dependent polarization switching behaviors of (111)-preferred polycrystalline Pb(ZrxTi1-x)O3 thin films with various Zr concentrations. We could explain al…
Ferroelectricity in artificial bicolor oxide superlattices
Sung Seok A. Seo, Jun Hee Lee, Ho Nyung Lee +7
We report on the growth and properties of high quality bicolor oxide superlattices, composed of two perovskites out of BaTiO3, CaTiO3, and SrTiO3. The artificially grown superlatti…
Electronic structures of hexagonal RMnO3 (R = Gd, Tb, Dy, and Ho) thin films
W. S. Choi, D. G. Kim, S. S. A. Seo +9
We investigated the electronic structure of multiferroic hexagonal RMnO3 (R = Gd, Tb, Dy, and Ho) thin films using both optical spectroscopy and first-principles calculations. Usin…
Orbital-Driven Electronic Structure Changes and the Resulting Optical Anisotropy of the Quasi-Two-Dimensional Spin Gap Compound La4Ru2O10
S. J. Moon, W. S. Choi, S. J. Kim +4
We investigated the electronic response of the quasi-two-dimensional spin gap compound La4Ru2O10 using optical spectroscopy. We observed drastic changes in the optical spectra as t…
Optical Study of the Free Carrier Response of LaTiO3/SrTiO3 Superlattices
S. S. A. Seo, W. S. Choi, H. N. Lee +4
We used infrared spectroscopic ellipsometry to investigate the electronic properties of LaTiO3/SrTiO3 superlattices (SLs). Our results indicated that, independent of the SL periodi…
