Journal ArticleDOI
Lanthanum-substituted bismuth titanate for use in non-volatile memories
TL;DR: In this paper, the authors show that lanthanum-substituted bismuth titanate (SBT) thin films provide a promising alternative for FRAM applications, since they are fatigue-free on metal electrodes, they can be deposited at temperatures of ∼650°C and their values of Pr are larger than those of the SBT films.
Journal ArticleDOI
Differences in nature of defects between SrBi2Ta2O9 and Bi4Ti3O12
Byung-Eun Park,S. J. Hyun,Sang Don Bu,Tae-Hee Noh,Jaichan Lee,Hoechang Kim,Tae Heon Kim,William Jo +7 more
TL;DR: In this paper, X-ray photoemission spectroscopy measurements were executed to compare the nature of defects in SrBi2Ta2O9 (SBT) and Bi4Ti3O12 (BTO) films.
Journal ArticleDOI
AFM study of the differential inhibitory effects of the green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG) against Gram-positive and Gram-negative bacteria
TL;DR: AFM results suggest that the major morphological changes of Gram-negative bacterial cell walls induced by EGCG depend on H( 2)O(2) release, while this is not the case for Gram-positive bacteria.
Journal ArticleDOI
In situ growth of superconducting MgB2 thin films with preferential orientation by molecular-beam epitaxy
TL;DR: In this paper, the authors reported the synthesis of superconducting MgB2 thin films grown in situ by molecular-beam epitaxy, where Mg-rich fluxes are deposited with B flux by electron-beam evaporation onto c-plane sapphire substrates.
Journal ArticleDOI
Magnetic ordering and spin-liquid state of YMnO3
Junghwan Park,J.-G. Park,J.-G. Park,Gun Sang Jeon,Han-Yong Choi,Changhee Lee,William Jo,Robert Bewley,K.A. McEwen,Toby Perring +9 more
TL;DR: In this article, the authors measured the elastic and inelastic properties of the Mn moments and showed that there are short range correlations between spins at the nearest neighbor and next nearest neighbor sites, which also fluctuate in time.
