Exotic magnetic anisotropy near digitized dimensional Mott boundary
Seung Gyo Jeong, Jihyun Kim, Taewon Min +8
The magnetic anisotropy of low-dimensional Mott systems exhibits unexpected magnetotransport behavior useful for spin-based quantum electronics. Yet, the anisotropy of natural mate…
Controlling spin-orbit coupling to tailor type-II Dirac bands
Nguyen Huu Lam, Phuong Lien Nguyen, Byoung Ki Choi +12
NiTe2, a type-II Dirac semimetal with strongly tilted Dirac band, has been explored extensively to understand its intriguing topological properties. Here, using density-functional…
Propagation control of octahedral tilt in SrRuO3 via artificial heterostructuring
Seung Gyo Jeong, Gyeongtak Han, Sehwan Song +8
Bonding geometry engineering of metal-oxygen octahedra is a facile way of tailoring various functional properties of transition metal oxides. Several approaches, including epitaxia…
Phase Instability amid Dimensional Crossover in Artificial Oxide Crystal
Seung Gyo Jeong, Taewon Min, Sungmin Woo +13
Artificial crystals synthesized by atomic-scale epitaxy provides the ability to control the dimensions of the quantum phases and associated phase transitions via precise thickness…
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…
Hole doping, hybridization gap, and electronic correlation in graphene on a platinum substrate
Jinwoong Hwang, Hwihyeon Hwang, Min-Jeong Kim +7
The interaction between graphene and substrates provides a viable routes to enhance functionality of both materials. Depending on the nature of electronic interaction at the interf…
