Structural models for amorphous arsenic

摘要

The arsenic is the main component of many chalcogenide systems. Arsenic and phosphorus are intermediate between the tetrahedral atoms (germanium, silicium, or carbon) and chalcogenide atoms (sulphur, selenium and tellurium). The structural properties of amorphus arsenic seem to be similar to those of the non-crystalline chalcogenides. That is why the investigation of the structure of amorphous arsenic could be of relevance for the structure of disordered chalcogenides
