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…
Ferroelectric polarization rotation in order-disorder-type LiNbO3 thin films
Tae Sup Yoo, Sang A Lee, Changjae Roh +16
The direction of ferroelectric polarization is prescribed by the symmetry of the crystal structure. Therefore, rotation of the polarization direction is largely limited, despite th…
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…
