Strongly Electric Field Dependent Conductivity in Quantum Dot Solids
Morteza Shokrani, Xinlu Wu, Ebbo Krahmer +1
Charge transport in QD solids is typically understood as thermally activated tunneling or hopping between states that are localized on individual QDs. Here, we show that the slow r…
Electric field-dependent conductivity as probe for charge carrier delocalization and morphology in organic semiconductors
Morteza Shokrani, Felix Maximilian Graf, Anton Kompatscher +2
The charge carrier localization length α is a crucial, yet often ignored parameter of conjugated polymers that exponentially influences electronic conductivity. Here, we argue it i…
Direct vs. Indirect Measurement of the Effective Electronic Temperature in Quantum Dot Solids
Anton Kompatscher, Morteza Shokrani, Johanna Feurstein +1
One of the characteristics of disordered semiconductors is the slow thermalization of charge carriers after excitation due to photoabsorption or high electric fields. An elegant wa…
A supramolecular ferroelectric with two sublattices and polarization dependent conductivity
H. Mager, M. Litterst, Sophia Klubertz +4
The possibility to combine and finetune properties of functional molecular materials by chemical design is particularly relevant for organic ferroelectrics. In this work, we invest…
Highly polar groups and supramolecular order enable charge injection and long-range conductivity in organic materials without extended π-systems
H. Mager, A. A. Butkevich, S. Klubertz +12
Electronic conductivity in organic materials is well-established. Both semiconductive and metallic behavior is observed in (quasi) 0-, 1-, 2- and 3-dimensional carbon-based materia…
