Influence of patterning on the nucleation of Ge islands on Si and SiO2 surfaces
Szkutnik, Pierre-David, Sgarlata, Anna, Motta, Nunzio, Placidi, E., Berbezier, Isabelle, & Balzarotti, Adalberto (2007) Influence of patterning on the nucleation of Ge islands on Si and SiO2 surfaces. Surface Science, 601(13), pp. 2778-2782.
Surface patterning is expected to influence the nucleation site of deposited nanostructures. In the present study, clean Si and SiO2 surfaces were patterned by a nanolithographic process using a Focused Ion Beam (FIB). Ge was evaporated in ultra high vacuum at 873 K on these substrates, resulting in the formation of island arrays. Based on scanning tunneling microscopy and atomic force microscopy images, a statistical analysis was performed in order to highlight the effect of patterning on the size distribution of islands compared to a non-patterned surface. We find that the self-organization mechanism on patterned substrates results in a very good arrangement and positioning of Ge nanostructures, depending on growth conditions and holes distance, both on Si and SiO2 surfaces.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
