Influence of transfer residue on the optical properties of chemical vapor deposited graphene investigated through spectroscopic ellipsometry

Graphene is the material of the future. Our group in collaboration with Serbian partners have examined the effects of transfer residue and sample annealing on the optical properties of chemical vapor deposited graphene, transferred onto a sapphire substrate. The optical … Continue reading

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
