Debye function analysis of structure in diffraction from nanometer-sized particles

Abstract

The special features of diffraction from particles in the nanometer size range are discussed and the problem of structure determination is considered. A direct method of structure analysis, known as Debye Function Analysis, is presented and evaluated. The method is capable of obtaining information about both the size and structure of domains in a sample, and can identify noncrystalline structures. Numerical simulations of observations are used to investigate the limitations of the technique, and also provide a general method for quantifying uncertainties in parameters estimated by Debye Function Analysis.
