Abstract | Thin strain-relaxed Si0.8Ge0.2 films (57.6 nm) on the 30 keV Ar+ ion implantation Si substrates for different dose (1 x 10(14), 5 x 10(14), 3 x 10(15) cm(-2)) were grown by ultra high vacuum chemical vapor deposition (UHVCVD) system. Rutherford backscattering/ion channeling (RBS/C), high resolution X-ray diffraction (HRXRD), Raman spectra as well as atomic force microscopy (AFM) were used to characterize these SiGe films. Investigations by RBS/C as well as HRXRD demonstrate that these thin Si0.8Ge0.2 films could indeed epitaxially grow on the Ar+ ion implantation Si substrates. Under low dose (1 x 10(14) cm(-2)) and medium dose (5 x 10(14) cm(-2)) implantation conditions, the relaxation extents of SiGe films are 60.6% and 63.6%, respectively. However, high dose implantation (3 x 10(15) cm(-2)) prompt the strain in epitaxial SiGe film to be close to full relaxation status (relaxation extent of 96.6%). On the other hand, determinations of RBS/C also indicate the crystalline quality of SiGe film grown on high dose implantation Si substrate is nearly identical to that grown on low dose (1 x 10(14) cm(-2)) implantation Si substrate. |
