The structure and properties of vacancies in Si nano-crystals calculated by real-space pseudopotential methods
S. P. Beckman, James R. Chelikowsky
The structure and properties of vacancies in a 2 nm Si nano-crystal are studied using a real space density functional theory/pseudopotential method. It is observed that a vacancy's…
