Large scale and linear scaling DFT with the CONQUEST code
Ayako Nakata, Jack Baker, Shereif Mujahed +8
We survey the underlying theory behind the large-scale and linear scaling DFT code, Conquest, which shows excellent parallel scaling and can be applied to thousands of atoms with e…

Highly accurate local basis sets for large-scale DFT calculations in CONQUEST
David R. Bowler, Jack S. Baker, Jack T. L. Poulton +5
Given the widespread use of density functional theory (DFT), there is an increasing need for the ability to model large systems (beyond 1,000 atoms). We present a brief overview of…

Structural properties of Silicon-Germanium and Germanium-Silicon Core-Shell Nanowires
Conn O'Rourke, Shereif Y. Mujahed, Chathurangi Kumarasinghe +2
Core-shell nanowires made of Si and Ge can be grown experimentally with excellent control for different sizes of both core and shell. We have studied the structural properties of S…
