Thermal Conductance across Phosphonic Acid Molecules and Interfaces: Ballistic versus Diffusive Vibrational Transport in Molecular Monolayers
John T. Gaskins, Anuradha Bulusu, Anthony J. Giodano, John C. Duta, Samuel Graham, and Patrick E. Hopkins Abstract The influence of planar organic linkers on thermal boundary conductance across hybrid interfaces has focused on the organic/inorganic interaction energy rather than on vibrational mechanisms in the molecule. As a result, research into interfacial transport at planar […]
Interface engineering of molecular charge storage dielectric layers fo organic thin-film memory transistors
Artoem Khassanov, Thomas Schmaltz, Hans-Georg Steinrück, Andreas Magerl, Andreas Hirsch, and Marcus Halik. Abstract Mixed self-assembled monolayers of C60-functionalized and different long-chained insulating phosphonic acids provide molecular scale non-volatile memory dielectrics for low-voltage organic thin-film transistors. The memory retention depends on the insulation of the C60 moiety and can be improved by embedding into the […]
Driving forces for the self-assembly of graphene oxide on organic monolayers
Johannes Kirschner, Zhenxing Wang, Siegfried Eigler, Han-Peter Steinrück, Christof M. Jäger, Timothy Clark, Andreas Hirsch and Marcus Halik Abstract Graphene oxide (GO) flakes were self-assembled from solution on surfaces of self-assembled monolayers (SAMs), varying in the chemical structure of their head groups. The coverage density of GO relates to strength of attractive interaction, which is […]

Study ofWet Surface Activation Routes to Enable the Deposition of Monomolecular Organic Thin Films on k 2.0 Porous Dielectrics
S. Armini, J. Loyo Prado, M. Krishtab, T. Conard, J. Meersschaut, Q. T. Le, P. Verdonck, and M. R. Baklanov Abstract This paper explores the effects of different wet surface treatments on low dielectric constant (low-k) materials and the consequences for the growth behavior of self-assembled monolayers (SAMs) from 11-cyanoundecyltrichlorosilane precursor on these modified substrates.
