Ab initio study of the double row model of the Si(553)-Au reconstruction
Sampsa Riikonen, Daniel Sanchez-Portal
Using x-ray diffraction Ghose et al. [Surf. Sci. {\bf 581} (2005) 199] have recently produced a structural model for the quantum-wire surface Si(553)-Au. This model presents two pa…

Metal-insulator transition in the In/Si(111) surface
Sampsa Riikonen, Andres Ayuela, Daniel Sanchez-Portal
The metal-insulator transition observed in the In/Si(111)-4x1 reconstruction is studied by means of ab initio calculations of a simplified model of the surface. Different surface b…

Structural models for the Si(553)-Au atomic chain reconstruction
Sampsa Riikonen, Daniel Sanchez-Portal
Recent photoemission experiments on the Si(553)-Au reconstruction show a one-dimensional band with a peculiar ~1/4 filling. This band could provide an opportunity for observing lar…
