A New Phosphorus Allotrope with Direct Band Gap and High Mobility
W. H. Han, Sunghyun Kim, In-Ho Lee +1
Based on ab initio evolutionary crystal structure search computation, we report a new phase of phosphorus called green phosphorus (λ-P), which exhibits the direct band gaps ranging…

Direct band gap carbon superlattices with efficient optical transition
Young Jun Oh, Sunghyun Kim, In-Ho Lee +2
We report pure carbon-based superlattices that exhibit direct band gaps and excellent optical absorption and emission properties at the threshold energy. The structures are nearly…

A Finite-Size Supercell Correction Scheme for Charged Defects in One-Dimensional Systems
Sunghyun Kim, Ji-Sang Park, K. J. Chang
We propose a new finite-size correction scheme for the formation energy of charged defects and impurities in one-dimensional systems within density functional theory. The energy co…
