Journal ArticleDOI
The Role of Intrinsic Defects in Methylammonium Lead Iodide Perovskite.
TL;DR: The results explain why the perovskite MALHs can be an efficient semiconductor, even when grown using simple solution processes, and suggest that the n-/p-type can be efficiently manipulated by controlling growth processes.
Journal ArticleDOI
First-principles investigation of the very large perpendicular magnetic anisotropy at Fe|MgO and Co|MgO interfaces
TL;DR: In this paper, the perpendicular magnetic anisotropy (PMA) arising at the interface between ferromagnetic transition metals and metallic oxides was investigated via first-principles calculations.
Journal ArticleDOI
Spin-canting-induced improper ferroelectricity and spontaneous magnetization reversal in SmFeO3.
Jung-Hoon Lee,Young Kyu Jeong,Jung Hwan Park,Min-Ae Oak,Hyun M. Jang,Jong Yeog Son,James F. Scott +6 more
TL;DR: First-principles calculations indicate that the canted antiferromagnetic ordering with two nonequivalent spin pairs is responsible for this extraordinary polarization and that the reverse Dzyaloshinskii-Moriya interaction dominates over the exchange-striction mechanism in the manifestation of the improper ferroelectricity.
Journal ArticleDOI
Resolving the Physical Origin of Octahedral Tilting in Halide Perovskites
Jung-Hoon Lee,Nicholas C. Bristowe,June Ho Lee,Sung-Hoon Lee,Paul D. Bristowe,Anthony K. Cheetham,Hyun M. Jang +6 more
TL;DR: In this paper, the authors re-examine the origin of octahedral tilts in halide perovskites from systematic first-principles calculations and find that while steric effects dominate the tilt magnitude in inorganic halides, hydrogen bonding between an organic A-cation and the halide frame plays a significant role in hybrids.
Journal ArticleDOI
Cooperative carbon capture and steam regeneration with tetraamine-appended metal–organic frameworks

Neaton,Jeffrey B. Neaton,Jeffrey A. Reimer,Jeffrey A. Reimer,Simon C. Weston,Jeffrey R. Long,Jeffrey R. Long +17 more
TL;DR: A family of robust tetraamine-functionalized frameworks that retain cooperativity are reported, leading to the potential for exceptional efficiency in capturing CO2 under the extreme conditions relevant to natural gas flue emissions.
