Fractionally delta-doped oxide superlattices for higher carrier mobilities
Woo Seok Choi, Suyoun Lee, Valentino R. Cooper +1
A 2D electron gas system in an oxide heterostructure serves as an important playground for novel phenomena. Here, we show that, by using fractional delta-doping to control the inte…
Room-temperature multiferroic hexagonal LuFeO films
Wenbin Wang, Jun Zhao, Wenbo Wang +15
The crystal and magnetic structures of single-crystalline hexagonal LuFeO films have been studied using x-ray, electron and neutron diffraction methods. The polar structure of…
Strain-Induced Spin States in Atomically Ordered Cobaltites
Woo Seok Choi, Ji-Hwan Kwon, Hyoungjeen Jeen +9
Epitaxial strain imposed in complex oxide thin films by heteroepitaxy is recognized as a powerful tool for identifying new properties and exploring the vast potential of materials…
Strongly coupled phase transition in ferroelectric/correlated electron oxide heterostructures
Lu Jiang, Woo Seok Choi, Hyoungjeen Jeen +2
We fabricated ultrathin ferroelectric/correlated electron oxide heterostructures composed of the ferroelectric Pb(Zr0.2Ti0.8)O3 and the correlated electron oxide (CEO) La0.8Sr0.2Mn…
Band gap tuning in ferroelectric Bi4Ti3O12 by alloying LaTMO3 (TM = Ti, V, Cr, Mn, Co, Ni, and Al)
Woo Seok Choi, Ho Nyung Lee
We fabricated ferroelectric Bi4Ti3O12 (BiT) single crystalline thin films site-specifically substituted with LaTMO3 (TM = Al, Ti, V, Cr, Mn, Co, and Ni) on SrTiO3 substrates by pul…
Wide band gap tunability in complex transition metal oxides by site-specific substitution
Woo Seok Choi, Matthew F. Chisholm, David J. Singh +3
Fabricating complex transition metal oxides with a tuneable band gap without compromising their intriguing physical properties is a longstanding challenge. Here we examine the laye…
