Stretching Epitaxial La0.6Sr0.4CoO3-δ for Fast Oxygen Reduction
Dongkyu Lee, Ryan Jacobs, Youngseok Jee +7
The slow kinetics of the oxygen reduction reaction (ORR) is one of the key challenges in developing high performance energy devices, such as solid oxide fuel cells. Straining a fil…
Direct Probing of Polarization Charges at the Nanoscale
Owoong Kwon, Daehee Seol, Dongkyu Lee +8
Ferroelectric materials possess spontaneous polarization that can be used for multiple applications. Owing to a long term development for reducing the sizes of devices, the prepara…
Charge transfer in iridate-manganite superlattices
Satoshi Okamoto, John Nichols, Changhee Sohn +3
Charge transfer in superlattices consisting of SrIrO and SrMnO is investigated using density functional theory. Despite the nearly identical work function and non-polar int…
Electronic and magnetic properties of epitaxial SrRhO3 films
John Nichols, Simuck F. Yuk, Changhee Sohn +4
Strong interplay of fundamental order parameters in complex oxides are known to give rise to exotic physical phenomena. The 4d transition metal oxide SrRhO3 has generated much inte…
Room-temperature relaxor ferroelectricity and photovoltaic effects in SnTiOx/Si thin film heterostructures
Radhe Agarwal, Yogesh Sharma, Siliang Chang +8
We have studied ferroelectricity and photovoltaic effects in atomic layer deposited (ALD) 40-nm thick SnTiO films deposited directly onto p-type (001)Si substrate. These film…
Full Electroresistance Modulation in a Mixed-Phase Metallic Alloy
Z. Q. Liu, L. Li, Z. Gai +11
We report a giant, ~22%, electroresistance modulation for a metallic alloy above room temperature. It is achieved by a small electric field of 2 kV/cm via piezoelectric strain-medi…
