High-field scanning probe lithography in hexadecane:: Transitioning from field induced oxidation to solvent decomposition through surface modification

High field scanning probe lithography in hexadecane leads to two different chemical reactions depending on surface hydrophilicity. On a hydrophilic surface, oxidation of the sample occurs; a hydrophobic surface, results in solvent decomposition and nanoscale deposition of etch resistant material. The features are characterized with photoelectron emission microscopy and are carbonaceous in nature with a highly cross-linked bonding network. Tone reversal in a fluorinated etch is achieved.
