This paper is about the stability of PEDOT coatings under high loads of current pulses. Test parameters were chosen to match many peripheral nervous system (PNS) applications in regard of charge injection, pulse width and repetition frequency. PEDOT coatings were characterized with electrochemical impedance spectroscopes (EIS) and pulse tests. No decrease in charge injection capacities could be...

Abstract Hydrogen adsorbed on a graphene electrode in contact with an aqueous solution is metastable state. Here, its desorption induced by small positive charge pulse was studied molecular dynamics tight binding method based density functional theory. The efficiency of the code allowed to follow trajectory desorbed particle detail. Desorption triggered oxygen atom water, which attracted surfac...

We demonstrated modulation of charge carrier densities in all-solution-processed organic field-effect transistors (OFETs) by modifying the injection properties with self-assembled monolayers (SAMs). The all-solution-processed OFETs based on an n-type polymer with inkjet-printed Ag electrodes were fabricated as a test platform, and the injection properties were modified by the SAMs. Two types of...

A detailed analysis of the dc behavior of switched-capacitor common-mode feedback circuit (SC-CMFB) is presented. A mathematical model, useful for analysis, is developed and the expressions for the output common-mode (CM) voltage, with and without considering the charge injection of switches and leakage currents, are derived. Further, the expression for dc CM settling time, is presented. The ef...

In order to reduce minimum operating voltage (VDDmin) of CMOS logic circuits, a new method reducing the within-die random threshold (VTH) variation of transistors by a post-fabrication automatically selective charge injection using substrate hot electrons (SHE) is proposed along with novel circuitry to utilize this. In the new circuit, switches are added to combinational logic circuits in order...

Injection from metallic electrodes serves as a main channel of charge generation in organic semiconducting devices and the quantum effect is normally regarded essential. We develop dynamic approach based upon surface-hopping (SH) algorithm classical device modeling, by which both tunneling thermionic emission charge-carrier injection at metal-organic interfaces are concurrently investigated. Th...
