Semiconducting materials (Electronic Materials) is crystalline solids, but amorphous and liquid semiconductors. These include hydrogenated amorphous silicon and mixtures of arsenic, selenium and tellurium in a variety of proportions. Such compounds share with better known semiconductors intermediate conductivity and a rapid variation of conductivity with temperature, as well as occasional negative resistance.

Disordered materials

Disordered materials lack the rigid crystalline structure of conventional semiconductors as silicon and are generally used in thin film structures, which are less demanding for as concerns the electronic quality of the material & thus are relatively insensitive to impurities, radiation damage. Organic semiconductors, that is, organic materials with properties resembling conventional semiconductors...
