Materials Research Society Symposia Proceedings 205: 33-38.0272-9172http://nrs.harvard.edu/urn-3:HUL.InstRepos:2859903We have measured the effects of hydrostatic pressure on the solid phase epitaxial growth (SPEG) rates of undoped GE(100) into their respective self-implanted amorphous volumes equal to -3.3 +/- 0.3cm³/mole for Si and -6.3 +/- 0.60cm³/mole for Ge. The results of this and other experiments are inconsistent with all bulk point-defect mechanisms, but are consistent with all interface point-defect mechanisms proposed to date for thermal SPEG. A kinetic analysis of the Spaepen-Turnbull bond mechanism shows it to be a highly plausible model for the growth process.en-US10.1063/1.103053
