TL;DR: In this paper, an investigation of the electrical and optical properties of amorphous thin films of alloys in the pseudo-binary system (As2S3)1−x(PbS)x (x = 0, 01, 04 and 05) prepared by flash evaporation has been carried out.

TL;DR: In this paper, the bipolaron formation in a two-dimensional lattice with harmonic confinement was investigated by means of quantum Monte Carlo simulations, which treated all interactions exactly and took into account quantum lattice fluctuations.
Abstract: Bipolaron formation in a two-dimensional lattice with harmonic confinement, representing a simplified model for a quantum dot, is investigated by means of quantum Monte Carlo simulations. This method treats all interactions exactly and takes into account quantum lattice fluctuations. Calculations of the bipolaron binding energy reveal that confinement opposes bipolaron formation for weak electron-phonon coupling, but abets a bound state at intermediate to strong coupling. Tuning the system from weak to strong confinement gives rise to a small reduction of the minimum Frohlich coupling parameter for the existence of a bound state.

TL;DR: In this article, evidence for electrochemical n-type doping of poly(2,5-thienylene vinylene) (PTV) was obtained from in situ measurements of a cyclic voltammogram, optical absorption spectrum and electron spin resonance.
Abstract: Evidence for electrochemical n-type doping of poly(2,5-thienylene vinylene) (PTV) is obtained from in situ measurements of a cyclic voltammogram, optical absorption spectrum and electron spin resonance. Bipolaron levels in the gap states appear upon n-type doping and the electronic band scheme of PTV is discussed.
