Graphene field-effect transistor structures were used to investigate the role of molecular alignment on charge transport properties of heterostructures comprising a single-layer graphene and variable thickness of N,N′-bis(n- octyl)-(1,7&1,6)-dicyanoperylene-3,4:9,10-bisdicarboximide (PDI8-CN2) – an n-type organic semiconductor. Our atomic force microscopy data … Continue reading →

Our research on mixed ion-electron conductivity involved us into a collaboration to develop a histamine biosensor. High concentrations of histamine are associated with subacute ruminal acidosis, a common disease in high-producing lactating dairy cows. Therefore, the accurate detection of low … Continue reading →

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 →

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 →

The researchers of Laboratory for Organic Matter Physics, University of Nova Gorica dr. Egon Pavlica and prof. dr. Gvido Bratina, together with colleagues from the University of Strasbourg, France, Humboldt University in Berlin, Germany and Stanford University, USA, have published … Continue reading →

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 →
