Edge-driven transition in surface structure of nanoscale silicon

Sohrab Ismail-Beigi, T. A. Arias

We present an ab initio exploration of the phenomena which will become important for freestanding structures of silicon as they are realized on the nanoscale. We find that not only…

Paramagnetic structure for the soliton of the $3 0^{\circ}$ partial dislocation in silicon

Gabor Csanyi, Sohrab Ismail-Beigi, T. A. Arias

Based on ab initio calculation, we propose a new structure for the fundamental excitation of the reconstructed 30 $^{\circ}$ partial dislocation in silicon. This soliton has a rare st…

On the Locality of Physics in Metals, Semiconductors, and Insulators

Sohrab Ismail-Beigi, Tomas Arias

We present an analytical study of the spatial decay rate $γ$ of the one-particle density matrix $ρ (r, r^{'}) \sim exp (- γ ∣ r - r^{'} ∣)$ for systems described by single part…
