Abstract

Nanoparticles in the recent times have drawn more attention in the field of electronics and in particular their property of self assembly over another material surface makes them a suitable component in the development of Nanoscale materials. Self organization property of Nanoparticles has opened up whole new possibilities in the construction of 2D nanostructures through deposition of organized bilayer of surfactant called black films on a solid substrate. Newton Black Films which are much thinner than a Common Black Films attracted more interests recently with their ability to form more complex structures. In this article, Newton Black films of POPC (1-palmitoyl-2-oleoyl-phosphaticylcholine) surfactant is formed and deposited on a solid substrate after a certain amount of time and their surface structure were analyzed with time. The experiment is conducted at three different drainage states; un-dried, un-dried with a salt present, and dried; their results are compared with MIES and UPS spectrum. Where, MIES spectra being more sensitive towards surface modification show that the structure becomes more ordered with drainage time and the process gets even faster with the addition of a salt. Comparatively, in MIES the presence of new elements is more clearly observed with the variation in their energy spectra on the drained film substrate than in the un-drained substrate owing to the fact that the drained film has more patterned outermost layer comprised with the new elements.
