Enhancement of electrical conductivity of poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) by a change of solvents

TL;DR: In this paper, the authors measured the DC conductivity of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(4-styrenesulfonate) (PSS) with various organic solvents.
Journal ArticleDOI

Flexible and transparent organic film speaker by using highly conducting PEDOT/PSS as electrode

TL;DR: In this article, a flexible organic film speaker (FOFS) was fabricated with ion-assisted reaction (IAR) treated poly(vinylidene fluoide) (PVDF) as active layer and poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate)(PEDOT/PSS), indium tin oxide (ITO), or copper (Cu) as electrode.
Journal ArticleDOI

Organic Based Flexible Speaker Through Enhanced Conductivity of PEDOT/PSS with Various Solvents

TL;DR: In this paper, a flexible organic film speaker was fabricated with ion assisted reaction (IAR) treated poly (vinylidene fluoide) (PVDF) as active layer and poly (3,4-ethylenedioxythiophene)/poly (4-styrenesulfonate) (PSS), indium tin oxide (ITO) and Cu as electrodes DC conductivity (σ DC ) of pristine PEDOT/PSS increases from 08 to 80 S/cm with adding various organic solvents [dimethyl sulfoxide (DMS
Journal ArticleDOI

Preparation of new semiconducting tetraphenylethynyl porphyrin derivatives and their high-performing organic field-effect transistors

TL;DR: In this paper, the design and synthesis of new solution processable semiconducting π-extended porphyrin derivatives H2TPEP and ZnTPEP were introduced and their use in the fabrication of high-performing thin film and single-crystal OFET devices were described.
Journal ArticleDOI

Characterization of GaN nanowires and light-emitting devices based on a GaN nanowire-PVK nanocomposite

TL;DR: In this paper, high-quality GaN nanowires have been synthesized by applying the laser ablation method, and the light emitting devices (LEDs) with the structure of ITO-coated glass/PEDOT:PSS/GaN-nodes/PVK nanocomposites/DCM-doped Alq 3 /Li:Al have been fabricated and examined together with the investigations of luminescence and device characteristics.
