ABSTRACT: We successfully fabricated
uniformly aligned polyurea thin films using molecular layer
deposition (MLD) technique. By measuring the film thickness as a functional of
the number of cycles, we confirmed the linear growth behavior of the polyurea MLD film. We also fabricated a
spin-coated polyurea films after synthesis of the polyurea polymer in solution, and compared
their roughness and surface potential with the prepared MLD film. The polyurea MLD film had a low root-mean
square value and homogeneous surface potentials, whereas the spin-coated film
had very rough surface and a highly variable surface potential. We believe that
our results will contribute to performance improvement of polymer-based
electrical devices and provide greater insight into the fabrication of
uniformly aligned polymer thin films.
