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…
Carrier and strain tunable intrinsic magnetism in two-dimensional MAX transition metal chalcogenides
Bheema Lingam Chittari, Dongkyu Lee, Allan H. MacDonald +2
We present a density functional theory study of the carrier-density and strain dependence of magnetic order in two-dimensional (2D) MAX (M= V, Cr, Mn, Fe, Co, Ni; A= Si, Ge, Sn…
