Abstract
Studies of amorphous (a‐) semiconductors have been driven by technological advances as well as fundamental theories. Observation of electrical switching, for example, fueled early interest in a‐chalcogenides. More recently a‐chalcogenide switching has been applied quite successfully to DVD technology where the quest for the discovery of better‐suited materials continues. Thus, switching grants researchers today with an active arena of technological as well as fundamental study. On the theoretical front, bond constraint theory and rigidity theory provide a powerful framework for understanding the structure and properties of a‐materials. Applications of these theories to switching in a‐chalcogenides holds the promise of finding the best composition suited for switching applications. EXAFS spectroscopy is an ideally suited technique to investigate the switching properties of these materials. Results of previous EXAFS experiments will be presented and viewed through the lens of bond constraint theory.
