  • Ordered Particle Arrays via a Langmuir Transfer Process: Access to Any Two-Dimensional Bravais Lattice.
    Langmuir, 2018
    Co-Authors: Miriam E. J. Hummel, Christian Stelling, Bernd A. F. Kopera, Fabian A. Nutz, Matthias Karg, Markus Retsch, Stephan Förster
    Abstract:

    We demonstrate how to directly transform a Close-Packed Hexagonal colloidal monolayer into nonClose-Packed particle arrays of any two-dimensional symmetry at the air/water interface. This major advancement in the field of nanoparticle self-assembly is based on a simple one-dimensional stretching step in combination with the particle array orientation. Our method goes far beyond existing strategies and allows access to all possible two-dimensional Bravais lattices. A key element of our work is the possibility to macroscopically stretch a particle array in a truly one-dimensional manner, which has not been possible up to now. We achieve this by stretching the nanoparticle array at an air/water interface during the transfer process. The degree of stretching is simply controlled by the wettability of the transfer substrate. To retain the symmetry of the transferred structure, the capillary forces upon drying have to be circumvented. We demonstrate two concepts based on thermal fixation for this. It allows for the first time to fabricate nonClose-Packed, nonHexagonal colloidal monolayers on a macroscopic length scale.
