AASERT94, Novel Materials and Devices from Self-Assembled Periodic Structures

Abstract

We request funding for one graduate student to work on a research program focused on developing new devices prepared from self-assembling submicron periodic structures. The work involves synthesis of new colloidal materials that can be used to create self-assembled sub micron periodicities, which will be used to develop new devices in the fields of optics, spectroscopy and separation science. We will create these submicron periodicities by utilizing the unique self-assembling property of monodisperse charged colloids; charged colloids self-assemble in solution to form BCC or FCC crystalline arrays (periodicities). We will examine the underlying physical phenomena responsible for this self-assembly process and will optimize the experimental conditions to prepare large defect free crystals. These crystals Bragg diffract light with extremely high efficiencies and are ideal for optical filtering applications.
