ON THE ELECTRONIC-STRUCTURE AND CONDUCTION PROPERTIES OF POLYMERIC QUASI-ONE-DIMENSIONAL MODEL SUPERLATTICES - STUDY OF TYPE-I AND TYPE-II-STAGGERED SUPERLATTICES

The electronic spectrum of the various quasi-one-dimensional model compositional superlattices (copolymers) (AmBn)x belonging to class of Type I and Type II-staggered superlattices have been calculated in the tight binding approximation using the direct numerical approach. The trends in their electronic structure and conduction properties as a function of (i) composition (m/n), (ii) block sizes m and n and (iii) arrangement of the blocks in the copolymer chain are discussed. The results obtained are important guidelines for designing copolymers with tailor made conduction properties. © 1992.
