Abstract:

Si1-x-yGexCy alloys have been actively investigated for use in heterojunction devices compatible with Si. Using the following values for the lattice constants of Si, Ge and C aSi0.54309 nm, aGe0.56576 nm and aC0.35667 nm, and assuming Vegards Law we obtain the condition on the ratio of Ge and C atomic fractions for lattice-matching to Si xy 8.2. For Ge1-yCy, binary alloys, the composition Ge0.89C0.11 is predicted to be lattice-matched to silicon. jg p.2
