One-Dimensional Phonons and "Phase-Ordering" Phase Transition in Hg 3 − δ As F 6

J. M. Hastings, +5 more
- 05 Dec 1977 - 
TL;DR: In this article, elastic and inelastic neutron-scattering studies on the incommensurate linear-chain mercury compound (Hg) have been performed at room temperature, and a transition from a randomly-phased interchain structure to a phase-ordered structure has been found and characterized.

Batteries having conjugated polymer electrodes

Alan G. MacDiarmid, +2 more
TL;DR: In this paper, conjugated polymers are doped with ionic dopant species to a preselected room temperature electrical conductivity ranging from that characteristic of semiconductor behavior to the characteristic of metallic behavior by means of reversible electrochemical doping procedures.
Journal ArticleDOI

Soliton lattice to metal: A first order phase transition

J. Chen, +3 more
- 01 Mar 1985 - 
TL;DR: In this article, in-situ measurements of the electron spin resonance of [Na+y (CH)−y]x during electrochemical doping are reported, and the susceptibility and the esr linewidth exhibit step-like increases with hysteresis, as functions of the chemical potential.
Journal ArticleDOI

Metal-polymer Schottky barriers on processible polymers

H. Tomozawa, +5 more
- 30 Jan 1989 - 
TL;DR: The results of a study of strong rectification by metal-polymer (Schottky) diodes made by evaporating metal contacts onto films of a soluble semiconducting polymer cast from solution were presented in this article.
Journal ArticleDOI

Solution-Processed pH-Neutral Conjugated Polyelectrolyte Improves Interfacial Contact in Organic Solar Cells

Huiqiong Zhou, +6 more
- 27 Jan 2015 - 
TL;DR: By utilizing a pH neutral, water/alcohol soluble conjugated polyelectrolyte CPE-K as the HTL in p-DTS(PTTh2)2:PC71BM solar cells, a 60% enhancement in PCE has been obtained with an increased V, reduced R, and improved charge extraction.
