| Abstract |
Molecular layer deposition (MLD) is sequential, self-limiting surface reaction to form conformal and ultra-thin polymer film. This technique typically uses bifunctional precursors for stepwise sequential surface reaction and entirely organic polymer films. In addition, in comparison with solution-based technique, because MLD is vapor-phase deposition based on ALD, it allows epitaxial growth of molecular layer on substrate and is especially good for surface reaction or coating of nanostructure such as nanopore, nanochannel, silica beads, nanowire array and so on.
In this study, organic-inorganic zincone polymeric films were fabricated through coupling reactions between diethylzinc (DEZ) and 2-butyne-1,4-diol (BYDO) as the inorganic and organic precursors, respectively. Molecular layer deposition based on sequential and self-limiting surface reactions was used to fabricate the films. Molecular geometries and surface binding energies were predicted by performing density functional theory (DFT) calculations. Depending on the surface energy of the substrates, SiO2(100) and Al2O3(1120), the difference in work functions of zincone MLD films was observed by scanning Kelvin probe microscopy (SKPM) measurements.
