Organic quantum well and superlattice characteristics in quasi-one-dimensional multiblock copolymers
Abstract
A tight-binding calculation was presented to describe multiblock copolymers, such as […-(PA) x -(PPP) y -…] composed of PA (polyacetylene) and PPP (poly( p-phenylene). It is found that a copolymer has a quantum well and superlattice characteristics, and evident is the effect of the composite lengths, the interfacial couplings and the electron-phonon interactions on the electronic properties of a copolymer. The quantum tunneling, the Franz-Keldysh effect and the quantum confinement can be generated under an applied electric field. These results were compared to those of traditional inorganic quantum well and superlattice systems.
