Thermopower enhancement by fractional layer control in 2D oxide superlattices
Woo Seok Choi, Hiromichi Ohta, Ho Nyung Lee
We have investigated two-dimensional thermoelectric properties in transition metal oxide heterostructures. In particular, we adopted an unprecedented approach to direct tuning of t…
Orienting oxygen vacancies for fast catalytic reaction
Hyoungjeen Jeen, Zhonghe Bi, Woo Seok Choi +4
Catalysis is indispensable to chemical processes and relevant to many aspects of modern life. Owing to the intriguing electronic structures and good ionic properties, multivalent t…
Topotactic phase transformation of the brownmillerite SrCoO2.5 to the perovskite SrCoO3-δ
Hyoungjeen Jeen, Woo Seok Choi, John W. Freeland +3
Oxygen stoichiometry is one of the most important elements in determining the physical properties of transition metal oxides (TMOs). A small fractional change in the oxygen content…
Multiple conducting carriers generated in LaAlO3/SrTiO3 heterostructures
S. S. A. Seo, Z. Marton, W. S. Choi +6
We have found that there is more than one type of conducting carriers generated in LaAlO3/SrTiO3 heterostructures by comparing the sheet carrier density and mobility from optical t…
