Renewed focus on the P-Si system due to its potential application in quantum computing and self-directed growth of molecular wires, has led us to study structural changes induced by P upon placement on Si(001)-$p(2\times 1)$. Using first-principles d

Possibility for the formation of stable Al atomic wire on the Si(211) surface is investigated using density functional theory based total energy calculations. The stable adsorption sites and the surface structures at various sub-monolayer coverages o

Electronic structure calculations for atomic wire of metals like Al, Ga and In are performed for a patterned dihydrogeneted Si(001):1 $\times$ 1 in search of structures with metallic behavior. The dihydrogeneted Si(001) is patterned by depassivating

Electronic structure calculations are performed to obtain the As-exposed Si(211) and the Te adsorbed As-exposed Si(211) surface. Arsenic-exposed Si(211) may be obtained by adsorbing As on Si(211) or by replacing surface Si atoms by As. First, we carr

Extensive electronic structure calculations are performed to obtain the stable geometries of metals like Al, Ga and In on the Si(001) surface at 0.5 ML and 1 ML coverages. Our results coupled with previous theoretical findings explain the recent expe
