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…

Dipole-Allowed Direct Band Gap Silicon Superlattices
Young Jun Oh, In-Ho Lee, Sunghyun Kim +2
Silicon is the most popular material used in electronic devices. However, its poor optical properties owing to its indirect band gap nature limit its usage in optoelectronic device…

Unbiased Global Optimization of Lennard-Jones Clusters for N <= 201 by Conformational Space Annealing Method
Julian Lee, In-Ho Lee, Jooyoung Lee
We apply the conformational space annealing (CSA) method to the Lennard-Jones clusters and find all known lowest energy configurations up to 201 atoms, without using extra informat…
