ScholarBank@NUS Repository. https://doi.org/10.1063/1.4747487||Abstract:||We present detailed observations of the solid phase epitaxy process in Sn-implanted Si samples with nanometric depth resolution within a 50 nm ultra-shallow region beneath the surface. Measurements were made using high-resolution Rutherford backscattering spectrometry coupled with the ion channeling technique. Samples with Sn ions implanted onto Si substrates with and without prior Si + self-amorphization implantation process show different crystal regrowth characteristics during annealing. Regrowth proceeds at a non-uniform rate up to a certain depth before stopping, and an Arrhenius-type defect density limiting model of crystal regrowth is proposed to account for this effect. © 2012 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/97961||ISSN:||00036951||DOI:||10.1063/1.4747487|
