Method of producing three dimensional assembly of particles in ordered arrays

摘要

A method of producing three dimensional ordered arrays of particles. The method may be used for the preparation of nanocomposite materials with highly periodic structures. More particularly the invention provides a method of producing three dimensional arrays based on applying a controlled oscillatory motion to settling dispersions of colloid particles. The controlled oscillatory motion is characterized by G=Aomega2/g, wherein g is the gravitational constant, A is the displacement and omega is angular frequency. G is maintained in the desired range by varying values of A within an effective range of displacements and &ugr; within an effective range of frequencies.
