| Research Abstract |
Patterned structures of colloidal nanoparticles are promising for various applications such as photonics, catalysis, biosensor, and transparent conductive materials, and a robust and scalable fabrication technique is missing and waits to be established. In the present study, we investigated the self-assembly process of particles into patterned structures via experiments and computer simulations. Our investigation demonstrated successful establishment of a pattern formation technique that can control the periodicity of striped and grid structures. Furthermore, direct observation and numerical simulations clarified the formation mechanism of stripe patterned structures of colloidal particles.
