| Abstract: | The effect of band widths of both valence and conduction bands of the homopolymers (A)x, (B)x and (C)x on the electronic properties of the model copolymers (AmBn)x and (AmCn)x has been investigated on the basis of the negative factor counting method in tight binding approximation. Using model band structures of three homopolymers (A)x, (B)x and (C)x, the electronic density of states (DOS) of their various periodic and aperiodic copolymers have been determined. On the basis of the band alignments of the constituent homopolymers, the copolymers (AmBn)x belong to the class of type-I while (AmCn)x belong to the class of type-II staggered. For both Type-I and Type-II staggered copolymers, three model systems differing in the band widths of the valence and conduction bands have been studied. The trends in the electronic structures and conduction properties of these copolymers as a function of band width are reported. |
