Flexible organic ion-gated transistors with low operating voltage and light-sensing application

Flexible low-voltage organic transistors based on a novel, high-mobility organic semiconductor

Organic thin-film transistors (TFTs) are of interest for a variety of large-area electronics applications, such as flexible active-matrix displays and conformable sensor arrays [1]. Among the challenges in the development of high-performance organic TFTs, especially on flexible polymeric substrates, is to realize organic TFTs that simultaneously provide a large field-effect mobility, a large on...

Ultra-low voltage air-stable polyelectrolyte gated n-type organic thin film transistors

High mobility, low voltage operating C60 based n-type organic field effect transistors

We report on C(60) based organic field effect transistors (OFETs) that are well optimized for low voltage operation. By replacing commonly used dielectric layers by thin parylene films or by utilizing different organic materials like divinyltetramethyldisiloxane-bis(benzocyclo-butene) (BCB), low density polyethylene (PE) or adenine in combination with aluminum oxide (AlOx) to form a bilayer gat...

Voltage-gated ion channels

differentiated newt cells, but not in their mammalian counterparts. There has been some progress along these lines but not at the level of pinpointing the genetic differences. It is important to remember that there are examples, such as the axolotl lens, where a particular tissue does not regenerate even though the animal is capable of regenerating other structures. Such a context may be more f...

Fluorinated polymer-grafted organic dielectrics for organic field-effect transistors with low-voltage and electrical stability.

The electrical stabilities of low-voltage organic field-effect transistors (OFETs) were improved by applying graftable fluorinated polymer (gPFS) layers onto poly(4-vinyl phenol)-based cross-linked dielectrics (cPVP). As a result, a smooth and hydrophobic surface was formed, and the dielectric film displayed a low-leakage current density. The chemisorbed gPFS groups enabled the solution process...
