DFT study of spin states on bare and partially hydrogenated Si(111) and Si(100) surfaces
Density functional theory calculations have been performed on slabs of crystalline silicon. The unreconstructed (111) and 2 x 1 reconstructed (100) surfaces have been studied. Starting from surfaces wholly passivated with hydrogen, selected sites were unpassivated to yield small clusters of unpaired spins corresponding to dangling bonds. A range of spin densities were converged for each cluster of dangling bonds to investigate the energetics of different spin patterns in these isolated clusters...[Show more]
