Abstract

Experimental results on light scattering and absorption in polyacetylene are reviewed, and interpreted in terms of the soliton model. The data indicate that injection of an electron-electron (hole-hole) pair by chemical doping or photoinjection of an electron-hole pair invariably distort the lattice leading to formation of a soliton-antisoliton pair. It is concluded that unlike traditional semiconductors, the polyacetylene lattice is inherently unstable in the presence of electron and/or hole excitations.
