Electronic transport, field effect and doping in pentacene nanorods and monolayer thin film prepared by combination of nano-fabrication and self-assembly [PDF]

, 2008
The transport in organic semiconductors is investigated on the nanometer scale. Field effect transistor with device-active layers in the monolayer (ML) range are characterized in-situ right after the controlled deposition of pentacene.

New Compact Modeling Solutions for Organic and Amorphous Oxide TFTs

IEEE Journal of the Electron Devices Society, 2021
We review recent compact modeling solutions for Organic and Amorphous Oxide TFTs (OTFTs and AOS TFTs, respectively), which were developed, under the framework of the EU-funded project DOMINO, to address issues specifically connected to the physics of ...

Approaching isotropic charge transport of n-type organic semiconductors with bulky substituents

Communications Chemistry, 2021
n-type organic semiconductors exhibiting two-dimensional isotropic charge transport are rarely reported. Here the authors show that using bulky substituents, BQQDI demonstrates near-isotropic charge transport, resilience to dynamic disorder, as well as ...

Self-standing chitosan films as dielectrics in organic thin-film transistors

eXPRESS Polymer Letters, 2013
Organic thin film transistors, using self-standing 50 µm thick chitosan films as dielectric, are fabricated using sublimed pentacene or two conjugated polymers deposited by spin coating as semiconductors.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Small contact resistance and high-frequency operation of flexible low-voltage inverted coplanar organic transistors

Nature Communications, 2019
The widespread adoption of organic thin-film transistors (TFTs) in low-voltage high-frequency device applications is impeded by the contact resistance in the TFTs.
