    Cymatics, proposed by Hans Jenny in 1967, is the study of the wave mechanics and visualization of sounds through vibrational phenomena of a plate surface. A famous example is the Chladni patterns, in which the powders or particles move due to the vibration and accumulate progressively at the nodal points of the applied wave, and thus lead to a spatially periodic arrangement.
    Professor Wooyoung Shim’s research group are motivated by the potential of cymatics to introduce a new approach to the assembly of micro- and nanomaterials that has been a long-standing goal in the field of nanoscience and nanoengineering in general. In this work, we utilize the combination of a silicon substrate as a vibrating surface and materials with different length scales from micrometer to nanometer and different geometries from particles to nanowires. Analogous to the definition of a crystallographic “lattice” symmetric and periodic points comprised of accumulated building blocks can be seen as a “lattice equivalent” resulting from the material assembly.
