摘要：

We present a theoretical study, based on Monte Carlo simulations, of the equilibrium structure and elastic properties of Si1-x-yGexCy alloys. We find a repulsive interaction among C substitutionals at short separations and, consistently with previous work, a preferred third nearest-neighbour-atom arrangement. Very few Ge-C bonds are found. We also observe significant deviations of the structural parameters of the system from linearly interpolated values. This effect is linked to a considerable downward bowing of the elastic constants of the material, as C is added.
