EXAFS STUDIES OF LIQUID SEMICONDUCTORS

EXAFS is a useful probe of studying the local structure of disordered systems. We have developed a new sample cell and carried out EXAFS mea surements for liquid semiconductors such as Se, Te and As2Se3, whose e lectronic properties often show metallic behaviour at high temperature s and pressures. EXAFS has been found to give useful information on th e neighboring configuration around a central atom as long as the atoms are covalently bonded.
