Abstract

A new ultrasonic radiation technique is described which facilitates the ordering of colloid particles into regular two-dimensional arrays. Ultrasonic radiation during the evaporation of the colloid solution enlarges the area of the particulate array and leads to a densely packed lattice reducing voids and random assemblies. Lattices of polystyrene particles (diameter: 64, 137, and 330 nm) and gold particles (diameter: 39 nm) were prepared under various ultrasonic powers. The arrays were imaged by the scanning electron microscope or the atomic force microscope.
