Vibronic response of a spin-1/2 state from a carbon impurity in two-dimensional WS
Katherine A. Cochrane, Jun-Ho Lee, Christoph Kastl +9
We demonstrate the creation of a spin-1/2 state via the atomically controlled generation of magnetic carbon radical ions (CRIs) in synthetic two-dimensional transition metal dichal…
Resonant and Bound States of Charged Defects in Two-Dimensional Semiconductors
Martik Aghajanian, Bruno Schuler, Katherine A. Cochrane +6
A detailed understanding of charged defects in two-dimensional semiconductors is needed for the development of ultrathin electronic devices. Here, we study negatively charged accep…
Reentrant Quantum Spin Hall States in Charge Density Wave Phase of Doped Single-Layer Transition Metal Dichalcogenides
Jun-Ho Lee, Young-Woo Son
Using first-principles calculation methods, we reveal a series of phase transitions as a function of electron doping in single-layer 1T-MoTe and 1T-WTe exhibiting qua…
Nature of the Insulating Ground State of the 5d PostPerovskite CaIrO3
Sun-Woo Kim, Chen Liu, Hyun-Jung Kim +4
The insulating ground state of the 5d transition metal oxide CaIrO3 has been classified as a Mott-type insulator. Based on a systematic density functional theory (DFT) study with l…
Antiferromagnetic Slater Insulator Phase of Na2IrO3
Hyun-Jung Kim, Jun-Ho Lee, Jun-Hyung Cho
Using a hybrid density-functional theory (DFT) calculation including spin-orbit coupling (SOC), we predict that the zigzag antiferromagnetic (AFM) ground state of the honeycomb lay…
Ferrimagnetic Slater Insulator Phase of the Sn/Ge(111) Surface
Jun-Ho Lee, Hyun-Jung Kim, Jun-Hyung Cho
We have performed the semilocal and hybrid density-functional theory (DFT) studies of the Sn/Ge(111) surface to identify the origin of the observed insulating ${\sqrt{3}}{\times}{\…
Antiferromagnetic ordering of dangling-bond electrons at the stepped Si(001) surface
Jun-Ho Lee, Sun-Woo Kim, Jun-Hyung Cho
Using first-principles density-functional calculations, we explore the possibility of magnetic order at the rebonded step of the Si(001) surface. The rebonded step cont…
Physisorption of DNA nucleobases on h-BN and graphene: vdW-corrected DFT calculations
Jun-Ho Lee, Yun-Ki Choi, Hyun-Jung Kim +2
We present a comparative study of DNA nucleobases [guanine (G), adenine (A), thymine (T), and cytosine (C)] adsorbed on hexagonal boron nitride (\textit{h}-BN) sheet and graphene,…
