Medium-range order in amorphous substances: A modified layer model

A conventional layer model for the first sharp diffraction peak (FSDP), a signature of medium-range order typical for a wide range of amorphous substances, is revised. It is proposed that the layers responsible for FSDP are based on alternative bonds, which are inherently connected with the basic bo...

Description
Summary:A conventional layer model for the first sharp diffraction peak (FSDP), a signature of medium-range order typical for a wide range of amorphous substances, is revised. It is proposed that the layers responsible for FSDP are based on alternative bonds, which are inherently connected with the basic bonds responsible for common short-range order in non-crystalline structure. Based on experimental FSDP data and simple chemical bond arguments the origin of alternative bonds is established in definite groups of amorphous substances: glasses, amorphous metals, liquids of different nature.
