First Principles Three-Dimensional Band-Structure of Trans-Polyacetylene

Abstract
The three-dimensional (3-D) band-structure of ideally crystalline trans-(CH)x is calculated self-consistently, with no adjustable parameter, using the LMTO-ASA method. The results are in good agreement with experiment. It is found that the quasi one-dimensional (1-D) behavior of the system is sensitive to the 3-D symmetry.
