Chalcogenides: Metastability and Phase Change Phenomena by Alexander V. Kolobov

By Alexander V. Kolobov

A state of the art description of metastability saw in chalcogenide alloys is gifted with the accessory at the underlying physics. A comparability is made among sulphur(selenium)-based chalcogenide glasses, the place a number of photo-induced phenomena happen solely in the amorphous part, and tellurides the place a reversible crystal-to-amorphous phase-change transformation is an immense influence. purposes of metastability in devices¿optical thoughts and nonvolatile digital phase-change random-access thoughts between others are mentioned, together with the most recent tendencies. history fabric crucial for knowing present study within the box can be provided.

5 Defects 21 and is electrically neutral. Such defects should be present in large quantities in an amorphous network consistent with the fact that the Fermi level in chalcogenide glasses is pinned near the middle of the gap [1]. At the same time, in amorphous chalcogenides a dark electron spin resonance (ESR) signal is usually not observed (with the exception of Ge-S glasses) whereas a large concentration of defect states has been demonstrated by techniques such as photoluminescence [47] and alternating current (ac) conductivity [48].

Any preferential ordering effects are neglected. Another often used model is the chemically ordered network (CON) model in which heteropolar bonds are favoured. It may be fair to say that as-deposited amorphous films that are fabricated under highly non-equilibrium conditions are better described by the CRN model while for well-annealed films and bulk glasses the CON model may be more appropriate. 2 Topological Defects Dangling Bonds Deviations from the 8–N rule give rise to topological defects in the CRN network of the glass.
