Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

New classes of polymers and oligomers whose backbone consists of a network of
delocalized π electrons have recently been synthesized and show electrical and non‐linear …

We distinguish between two classes of the emeraldine form of polyaniline. Class I
emeraldine is that forwhich the conducting HC1 salt exhibits ES-I crystal structure and the …

Fourier Transform IR transmission spectroscopy has been utilized to elucidate the nature of
the polymer–dopant interaction in doped (CH) x. Significant changes in the IR spectrum …

A reproducible current switching effect has been observed in various mixed‐stack organic
charge transfer crystals whose ionicities are close to the neutral‐ionic phase boundary. This …

Conducting polymers (CPs) provide a class of processible, film forming semiconductors and
metals. Electrical and optical properties of CPs, similar to those of metals and …

The many-body ground state of a very general class of electron-phonon Hamiltonians is
proven to contain a spin singlet (for an even number of electrons on a finite lattice). The …

The geometrical structures and vibrational spectra of all-trans, cis-transoid and trans-cisoid
polyacetylene, and all-trans-polymethineimine have been calculated using the energy …

The relaxation processes of self-trapped excitons (STE's) in halogen-bridged mixed-valence
metal complexes (MX-chain complexes) have been investigated by picosecond time …
