Improving the Performance of Organic Thin-Film Transistors by Ion Doping of Ethylene-Glycol-Based Self-Assembled Monolayer Hybrid Dielectrics

Hanno Dietrich, Simon Scheiner, Lui Portilla, Dirk Zahn, Marcus Halik Abstract Tuning the electrostatics of ethylene-glycol-based self-assembled monolayers (SAMs) by doping with ions is shown. Molecular dynamics simulations unravel binding mechanisms and predict dipole strengths of the doped layers. Additionally, by applying such layers as dielectrics in organic thin-film transistors, the incorporated ions are proven […]

Functionalization of silicon oxide using supercritical fluid depositionof 3,4-epoxybutyltrimethoxysilane for the immobilization of amino-modified oligonucleotide

Jordi Rull, Guillaume Nonglaton, Guillaume Costa, Caroline Fontelaye, Caroline Marchi-Delapierre, Stéphane Ménage, Gilles Marchand Abstract The functionalization of silicon oxide based substrates using silanes is generally performed through liquid phase methodologies. These processes involve a huge quantity of potentially toxic solvents and present some important disadvantages for the functionalization of microdevices or porous materials, for […]

Low-voltage self-assembled monolayer field-effect transistor on flexible substrates

Thomas Schmaltz, Atefeh Y. Amin, Artoem Khassanov, Timo Meyer-Friedrichsen, Hans-Georg Steinrück, Andreas Magerl, Juan José Segura, Kislon Voitchovsky ,Francesco Stellacci, and Marcus Halik. Abstract Self-assembled monolayer field-effect transistors (SAMFETs) of BTBT functionalized phosphonic acids are fabricated. The molecular design enables device operation with charge carrier mobilities up to 10−2 cm2 V−1 s−1 and for the […]
