On the electronics structures and conduction properties of quasi-one dimensional model compositional superlattices of type II-staggered

The electronic spectra of three different quasi-one dimensional model compositional superlattices (copolymers) (A(m)B(n))(x) belonging to the class of type-II staggered have been calculated in the tight binding approximation using a direct numerical approach. The trends in the structure and conduction properties as a function of (i) composition (m/n), (ii) block size m and n and (iii) arrangement of blocks in the copolymer chain for all the superlattices are discussed.
