Conformal single-layer encapsulation of PEDOT at low substrate temperature

Conformal Single-layer Encapsulation of PEDOT at Low Substrate Temperature

In this work, we demonstrate a single-layer encapsulation method for poly(3,4ethylenedioxythiophene) (PEDOT). This method is achieved by initiated chemical vapor deposition (iCVD) process, which is scalable and employs solvent-free and low-substrate temperature conditions. The encapsulant used, poly(divinylbenzene-co-maleic anhydride) (PDVB-MA), was first time synthesized via vapor phase proces...

Quadrature Hybrid Miniaturization on Single-Layer Substrate

This paper presents an exact design technique to obtain formulas for compact quadrature hybrid coupler. We minimize the physical size based on even-and odd mode analysis. The proposed structure is relatively simple as the coupler can be fabricated on a single-layer printed circuit board. After finishing the design, full prototype of proposed coupler is fabricated and tested to validate the desi...

Green Method for Synthesizing Gallium Nitride Nanostructures at Low Temperature

Gallium nitride (GaN) nanostructures (NS) were synthesized using pulseddirect current plasma enhanced chemical vapor deposition (PDC-PECVD) on quartzsubstrate at low temperature (600°C). Gallium metal (Ga) and nitrogen (N) plasma wereused as precursors. The morphology and structure of the grown GaN NS werecharacterized by field emission scanning electron microscope (FE-SEM), transmissionelectro...

PEDOT-CNT coated electrodes stimulate retinal neurons at low voltage amplitudes and low charge densities.

OBJECTIVE The aim of this study was to compare two different microelectrode materials--the conductive polymer composite poly-3,4-ethylenedioxythiophene (PEDOT)-carbon nanotube(CNT) and titanium nitride (TiN)--at activating spikes in retinal ganglion cells in whole mount rat retina through stimulation of the local retinal network. Stimulation efficacy of the microelectrodes was analyzed by compa...
