Pulsed-mode metalorganic vapor-phase epitaxy of GaN on graphene-coated c-sapphire for freestanding GaN thin films
Seokje Lee, Muhammad S. Abbas, Dongha Yoo +14
We report the growth of high-quality GaN epitaxial thin films on graphene-coated c-sapphire substrates using pulsed-mode metalorganic vapor-phase epitaxy, together with the fabrica…
Tuning orbital-selective phase transitions in a two-dimensional Hund's correlated system
Eun Kyo Ko, Sungsoo Hahn, Changhee Sohn +12
Hund's rule coupling () has attracted much attention recently for its role in the description of the novel quantum phases of multi orbital materials. Depending on the o…
Heteroepitaxial control of Fermi liquid, Hund metal, and Mott insulator phases in the single-atomic-layer limit
Jeong Rae Kim, Byungmin Sohn, Hyeong Jun Lee +16
Interfaces between dissimilar correlated oxides can offer devices with versatile functionalities. In that respect, manipulating and measuring novel physical properties of oxide het…
Observation of metallic electronic structure in a single-atomic-layer oxide
Byungmin Sohn, Jeong Rae Kim, Choong H. Kim +11
Correlated electrons in transition metal oxides (TMOs) exhibit a variety of emergent phases. When TMOs are confined to a single-atomic-layer thickness, experiments so far have show…
Importance of anisotropic Coulomb interactions in the electronic and magnetic properties of MnO
Sangmoon Yoon, Sangmin Lee, Subeen Pang +2
We report the importance of anisotropic Coulomb interactions in DFT+U calculations of the electronic and magnetic properties of MnO. The effects of anisotropic interactions…
Effects of paramagnetic fluctuations on the thermochemistry of MnO (100) surfaces in the oxygen evolution reaction
Sangmoon Yoon, Kyoungsuk Jin, Sangmin Lee +3
We investigated the effects of paramagnetic (PM) fluctuations on the thermochemistry of the MnO(100) surface in the oxygen evolution reaction (OER) using the "noncollinear magnetic…
Noncollinear magnetic sampling method for paramagnetic Mott insulator MnO
Sangmoon Yoon, Seoung-Hun Kang, Sangmin Lee +4
We present a new approach based on the static density functional theory (DFT) to describe paramagentic MnO, which is a representative paramagnetic Mott insulator. We appended the s…
