Flexoelectric control of a ferromagnetic metal
Wei Peng, Se Young Park, Chang Jae Roh +16
Electric fields have played a key role in discovering and controlling exotic electronic states of condensed matter. However, electric fields usually do not work in metals as free c…
Multiferroic-enabled magnetic exciton in 2D quantum entangled van der Waals antiferromagnet NiI2
Suhan Son, Youjin Lee, Jae Ha Kim +15
Matter-light interaction is at the center of diverse research fields from quantum optics to condensed matter physics, opening new fields like laser physics. A magnetic exciton is o…
Possible persistence of multiferroic order down to bilayer limit of van der Waals material NiI
Hwiin Ju, Youjin Lee, Kwang-Tak Kim +10
Realizing a state of matter in two dimensions has repeatedly proven a novel route of discovering new physical phenomena. Van der Waals (vdW) materials have been at the center of th…
Thermal transport evolution due to nanostructural transformations in Ga-doped indium-tin-oxide thin films
Alexandr Cocemasov, Vladimir Brinzari, Do-Gyeom Jeong +4
We report on a comprehensive theoretical and experimental investigation of thermal conductivity in indium-tin-oxide (ITO) thin films with various Ga concentrations (0-30 at. %) dep…
Linear magneto-electric phase in ultrathin MnPS probed by optical second harmonic generation
H. Chu, C. J. Roh, J. O. Island +7
The transition metal thiophosphates PS ( = Mn, Fe, Ni) are a class of van der Waals stacked insulating antiferromagnets that can be exfoliated down to the ultrathin limit…
Room Temperature Ferroelectric Ferromagnet in 1D Tetrahedral Chain Network
Kyeong Tae Kang, Chang Jae Roh, Jinyoung Lim +17
Ferroelectricity occurs in crystals with broken spatial inversion symmetry. In conventional perovskite oxides, concerted ionic displacements within a three-dimensional network of t…
Covalent-bonding-induced strong phonon scattering in the atomically thin WSe2 layer
Young-Gwan Choi, Do-Gyeom Jeong, H. I. Ju +6
In nano-device applications using 2D van der Waals materials, a heat dissipation through nano-scale interfaces can be a critical issue for optimizing device performances. By using…
