Summary

The purpose of this study was to investigate a novel self assembly on a mica surface. When the researchers allowed (dodecyldimethylammonioacetoxy)diethyltriamine trichloride (DTAD) to assemble on a mica surface nanoscaled parallel stripes formed. This interesting formation is quite unique compared to islands that form on normal surfaces. A suggested mechanism for this ordering was also proposed that draws on many different forces including hydrophbicity and lattice matching.
