| Abstract: | The effect of change in the ratio of conduction band discontinuity to the valence band discontinuity (ΔEc/ΔEv) on the electronic structures and conduction properties of model copolymers (AmBո)x, belonging to the class of Type-I quasi-one-dimensional superlattices are reported. Six different systems of copolymers (AmBո)x, differing in respect of the ratio ΔEc/ΔEv, have been modelled using the model band structure of constituent homopolymers (A)x and (B)x. For each of these systems of copolymers the electronic density of states of the various periodic and aperiodic copolymer chains have been determined on the basis of negative factor counting method in tight binding approximation. The trends obtained in the electronic structures and conduction properties of these copolymers as a function of the ratio ΔEc/ΔEv are useful guidelines for designing copolymers with desired electronic and conduction properties. |
