Cryogenic cleavage used in gold substrate production
Mazurkiewicz, Jakub, Mearns, Freya J., Losic, Dusan, Weeks, Laura, Waclawik, Eric R., Rogers, Craig T., Shapter, Joseph G., & Gooding, J. Justin (2002) Cryogenic cleavage used in gold substrate production. Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures, 20(6), pp. 2265-2270.
An improved method for the production of ultralarge flat and patterned gold surfaces for use in scanning probe studies using a procedure based on epitaxial gold growth on mica is described. The approach is superior in terms of simplicity and reliability without any loss of substrate quality. The gold surface is glued onto an aluminum stub with two part ceramic or polyester glue. The mica is removed by immersing the sample in liquid nitrogen. The liquid nitrogen causes differential contraction of the mica and gold resulting in clean separation to leave large atomically flat planes or patterned features.
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.
