Formation of metastable Si1-x-yGexCy layers (x = 0.13 and y = 0.014 at peak concentration) on Si(100) has been performed by high-dose implantation of 80 keV Ge and 17 keV C ions and subsequent ion-beam-induced epitaxial crystallisation (IBIEC) with 400 keV Ar or Ge ion bombardments at 300-400°C. Their structural properties are compared with those of Si1-x-yGexCy layers grown by solid phase epitaxial growth (SPEG) up to 700°C. Crystalline growth by IBIEC has shown a larger growth rate in Si1-x-yGexCy Si than in Si1-xGex Si with the same Ge concentration for all bombardments under investigation. Depth profiles of implanted atoms observed by SIMS measurements have revealed almost the same profiles for Ge and C atoms after IBIEC process. X-ray rocking curve measurements have shown a strain-compensated growth of Si1-x-yGexCy Si by IBIEC, whereas it has been suggested that Si1-x-yGexCy Si layers crystallised by SPEG have both compressive and tensile strains.
