Radial Distribution Function (RDF) is commonly used in statistical mechanics to understand several disordered systems such as amorphous solids, liquids, and gases. Unfortunately, determination of the RDF from the low energy X-Ray Diffraction (XRD) experiment consistently shows poor resolution. This research used Wavelet Transform (WT) method with our theoretically constructed Wavelet Function (WF) to solve the resolution problem and it shows good results in predicting interatomic distance and the RDF graph trend of the amorphous Ge0.25Se0.75 and Agx(Ge0.25Se0.75)100-x (x = 5, 10, 15, 20, 25). Although the WT method shows decent results for predicting the interatomic distance and RDF graph trend, further validation needs to be done. To give more validation, this research proposed to use Classical Density Functional Theory (CDFT) with Born-Meyer Type Potential (BMTP). BMTP which is known to represent the short-range atomic interaction is used in this research as an effective potential for the CDFT. It is because the amorphous materials have a very local atomic order and it happens because of the short-range interatomic interaction. In this research, it is found that the repulsion and attractive coefficients (A2 and A4) for Ge0.25Se0.75 are 5.93969 and 2.43213. Concurrently for Agx(Ge0.25Se0.75)100-x, the A2 and A4 values are consistent around 6.60-7.00 and 2.70-2.85. The BMTP geometries for Ge0.25Se0.75 and Agx(Ge0.25Se0.75)100-x are also similar to the potential in WT RDF. These BMTP geometries strongly support that the newly discovered WT method is valid.bstract.
