Intertwined Orders in a Quantum-Entangled Metal
Junyoung Kwon, Jaehwon Kim, Gwansuk Oh +18
Entanglement underpins quantum information processing and computing, yet its experimental quantification in complex, many-body condensed matter systems remains a considerable chall…
Interplay of canted antiferromagnetism and nematic order in Mott insulating Sr2Ir1-xRhxO4
Hyeokjun Heo, Jeongha An, Junyoung Kwon +4
Sr2IrO4 is one of the prime candidates for realizing exotic quantum spin orders owing to the subtle combination of spin-orbit coupling and electron correlation. Sensitive local mag…
Observation of Kondo hybridization with an orbital-selective Mott phase in 4d Ca2-xSrxRuO4
Minsoo Kim, Junyoung Kwon, Choong H. Kim +12
The heavy fermion state with Kondo-hybridization (KH), usually manifested in f-electron systems with lanthanide or actinide elements, was recently discovered in several 3d transiti…
Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
Evidence of structural evolution in Sr2RhO4 studied by time-resolved optical reflectivity spectroscopy
Min-Cheol Lee, Inho Kwak, Choong H. Kim +7
We investigate ultrafast dynamics from photoinduced reflectivity of Sr2RhO4 by using femtosecond near-infrared pulses. We observe a clear temperature-dependent anomaly in its elect…
Seamless monolithic three-dimensional integration of single-crystalline films by growth
Ki Seok Kim, Seunghwan Seo, Junyoung Kwon +16
The demand for the three-dimensional (3D) integration of electronic components is on a steady rise. The through-silicon-via (TSV) technique emerges as the only viable method for in…
Deep learning-based statistical noise reduction for multidimensional spectral data
Younsik Kim, Dongjin Oh, Soonsang Huh +13
In spectroscopic experiments, data acquisition in multi-dimensional phase space may require long acquisition time, owing to the large phase space volume to be covered. In such case…
Single crystal growth of iridates without platinum impurities
Jimin Kim, Hoon Kim, Hyun-Woo J. Kim +7
Iridates have attracted much interest in the last decade for their novel magnetism emerging in the limit of strong spin-orbit coupling and possible unconventional superconductivity…
High-performance monolayer MoS2 field-effect transistor with large-scale nitrogen-doped graphene electrodes for Ohmic contact
Dongjea Seo, Dong Yun Lee, Junyoung Kwon +8
A finite Schottky barrier and large contact resistance between monolayer MoS2 and electrodes are the major bottlenecks in developing high-performance field-effect transistors (FETs…
Electric field driven octahedral rotation in perovskite
Wonshik Kyung, Choong H. Kim, Yeong Kwan Kim +9
Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most imp…
