Abstract
Si1-x-yGexCy / Si heterostructures are realized by pulsed laser induced epitaxy (PLIE) from C+ implanted pseudomorphic Si0.84/Ge(subscript 0.16 films and from hydrogenated amorphous SiGeC films deposited on Si(100). The laser treated samples are examined by electron channeling, energy dispersive X-ray analysis, Rutherford backscattering spectroscopy, X-ray diffraction and Raman spectroscopy. First results show that laser induced epitaxy is effective, provided that laser fluence exceeds a threshold for which the melted depth is larger than the initial SiGeC layer. In addition, carbon incorporation in substitutional sites is demonstrated.
