摘要
We present molecular-dynamics simulations of the atomic arrangement in molten and amorphous germanium. We start with 512 atoms in a supercell and then heat it above the melting temperature. Subsequent rapid quenching results in a continuous random network (CRN) with a radial distribution function (RDF) in excellent agreement with the results from accurate diffraction experiments of other investigators. We analyze the topology of the molten and amorphous structures and present angular distribution functions, coordination number, and ring statistics.
