Title: | Critical aspects of alloying and stress relaxation in ge/si(100) islands | Authors: | Hadjisavvas, George C. Kelires, Pantelis C. |
Major Field of Science: | Engineering and Technology | Keywords: | Islands;Alloys | Issue Date: | 19-May-2005 | Source: | Physical Review B - Condensed Matter and Materials Physics, 2005, vol. 72, no. 7 | Volume: | 72 | Issue: | 7 | Journal: | Physical Review B | Abstract: | We report Monte Carlo simulations of alloying and stress relaxation in Ge/Si(100) dome and pyramidal islands. In both cases, the simulated composition profiles consist of inhomogeneous Si-rich cores and outer Ge-rich shells. Comparison to experimentally deduced profiles gives us the opportunity to discuss some of the most controversial aspects of the problem. We propose that, in addition to surface events and kinetically driven alloying, volume diffusion and stress-driven intermixing need to be considered for a global interpretation of experimental results. | URI: | https://hdl.handle.net/20.500.14279/1761 | ISSN: | 24699969 | DOI: | 10.1103/PhysRevB.72.075334 | Rights: | © The American Physical Society. | Type: | Article | Affiliation: | University of Crete | Affiliation : | University of Crete | Publication Type: | Peer Reviewed |
