摘要

It is known that both natural and syn-thetic solid materials can be classified into three categories:(i) crystalline solids,(ii)amorphous solids and (iii) crystalline-amorphous solids.Crystalline materi-als are also called ordered materials or crystals,since they feature long-range ordered structure,i.e.the periodic ar-rangement of lattice points.In contrast,amorphous materials can be referred to as disordered,and include gels,amorphous carbon and silicon,defect-rich solids,and melt-quenched (MQ) glasses,since their microstructure is disordered in the long range (i.e.beyond the scale of ca.2 nm).
