We investigate the structural trends of bulk amorphous Si1-xCx alloys
in the composition range 0.125<x <0.875 by molecular dynamics. Our sim
ulations, based on the many-body potential by Tersoff, allow for an ac
curate analysis of the compound topology, as well as of its chemical o
rder. We also characterize the local atomic coordination and network d
istortion as a function of the alloy composition. [S0163-1829(98)04640
