Journal ArticleDOI
Tunneling electroresistance effect in ferroelectric tunnel junctions at the nanoscale.
Alexei Gruverman,Dong Wu,Haidong Lu,Yong Wang,Ho Won Jang,C. M. Folkman,M. Ye. Zhuravlev,D. A. Felker,Mark Rzchowski,Chang-Beom Eom,Evgeny Y. Tsymbal +10 more
TL;DR: The obtained results show a change in resistance by about 2 orders of magnitude upon polarization reversal on a lateral scale of 20 nm at room temperature, promising for employing ferroelectric tunnel junctions in nonvolatile memory and logic devices.
Journal ArticleDOI
Ferroelastic switching for nanoscale non-volatile magnetoelectric devices
Seung Hyub Baek,Ho Won Jang,Chad M. Folkman,Yulan Li,B. Winchester,Jinxing Zhang,Qing He,Ying-Hao Chu,Christopher T. Nelson,Mark Rzchowski,Xiaoqing Pan,Ramamoorthy Ramesh,Long Qing Chen,Chang-Beom Eom +13 more
TL;DR: This work demonstrates a critical step to control and use non-volatile magnetoelectric coupling at the nanoscale and provides a framework for exploring a route to control multiple order parameters coupled to ferroelastic order in other low-symmetry materials.
Journal ArticleDOI

Blick,Chang-Beom Eom +24 more
TL;DR: In this paper, the authors synthesized high-quality PMN-PT epitaxial thin films on vicinal (001) Si wafers with the use of a template layer with superior piezoelectric coefficients (e31,f = −27 ± 3 coulombs per square meter).
Journal ArticleDOI
One-dimensional oxide nanostructures as gas-sensing materials: review and issues.
Kyoung Jin Choi,Ho Won Jang +1 more
TL;DR: This article reviews gas sensor application of one-dimensional (1D) metal-oxide nanostructures with major emphases on the types of device structure and issues for realizing practical sensors.
Journal ArticleDOI
Domain Engineering for Enhanced Ferroelectric Properties of Epitaxial (001) BiFeO Thin Films
Ho Won Jang,Daniel Ortiz,Seung Hyub Baek,Chad M. Folkman,Rasmi R. Das,Padraic Shafer,Yanbin Chen,C. T. Nelson,Xiaoqing Pan,Ramamoorthy Ramesh,Chang-Beom Eom +10 more
TL;DR: In this paper, a multiferroic BiFeO3 has attracted great interest due to its promising application in tomagnetoelectric devices, which is comparable to those of conventional Ti-rich lead zirconia titanate, and suggested BiO3 as a strong candidate for lead-free nonvolatile memories.
