Photo-induced intramolecular charge transfer in an ambipolar field-effect transistor based on a π-conjugated donor–acceptor dyad
Our research team collaborated in a photoconductivity characterization of an interesting dyad molecule. A π-conjugated tetrathiafulvalene-fused perylenediimide (TTF-PDI) molecular dyad is successfully used as a solution-processed active material for light sensitive ambipolar field-effect transistors with balanced hole and electron mobilities. … Continue reading

Extreme sensitivity to adsorbates of Time-of-Flight photoconductivity in graphene
We have examined the effect of submonolayer coverage of 1-pyrene butyric acid on charge carrier transport in reduced graphene oxide. We have modeled the interaction of 1-pyrene butyric acid molecules with graphene and determined the amount of charge transfer at … Continue reading

Grafold-driven nucleation of pentacene on graphene
Folds in graphene – grafolds are frequently present even after transferring graphene layers, which were fabricated by chemical vapor deposition (CVD), onto SiO2 substrates. As we are showing in the present Letter, grafolds have a crucial role in determining the … Continue reading

Time-of-flight mobility of charge carriers in position-dependent electric field
We explained the difference between charge mobility of time-of-flight measurement and field-effect measurement in a recent paper. Time-of-flight measurements of the photocurrent in thin organic semiconductor layers represent an effective way to extract charge carrier mobility. A common method to … Continue reading

Single-step processing of TES-ADT based transistors
Our lab was involved in a discovery of a simple, alternative route towards high-mobility structures of the small-molecular semiconductor 5,11-bis(triethyl silylethynyl) anthradithiophene – TES-ADT that requires one single processing step without the need for any post-deposition processing. The method relies … Continue reading
