Polycrystalline Semiconductors: Physical Properties and Applications: Proceedings of the International School of Materials Science and Technology at the Ettore Majorana Centre, Erice, Italy, July 1-15, 1984

In terms of structure, the field of semiconductors spans a wide range, from the perfect order of single crystals to the non-periodic, disordered amorph­ ous state. The two extremes of this range attract a large amount of inter­ est. On one side, glamorous novel phenomena are being found which can only occur in specially tailored ultra-perfect periodic lattices. On the other side, the exotic and challenging nature of the amorphous state has triggered a surge of activity in recent years. Po1y...
