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…
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,…
