چکیده
Coupled IonicElectronic Charge Transport in Organic Neuromorphic Devices In article number 2100492, Daniel Felder, John Linkhorst, Matthias Wessling, and co-workers describe the non-ideal behavior of organic neuromorphic devices by finite volume simulation. The models reveal impurities to cause device memory degradation write errors through parasitic electrochemical reactions. These results enable mitigation strategies towards robust neural networks on highly efficient hardware.

Numerical simulation of charge transport in disordered organic semiconductor devices
For the design of organic semiconductor devices such as organic light-emitting devices and solar cells, it is of crucial importance to solve the underlying charge transport equations efficiently and accurately. Only a fast and robust solver allows the use of fitting algorithms for parameter extraction and variation. Introducing appropriate models for organic semiconductors that account for the ...
متن کاملCharge transport in nanoscale vertical organic semiconductor pillar devices
We report charge transport measurements in nanoscale vertical pillar structures incorporating ultrathin layers of the organic semiconductor poly(3-hexylthiophene) (P3HT). P3HT layers with thickness down to 5 nm are gently top-contacted using wedging transfer, yielding highly reproducible, robust nanoscale junctions carrying high current densities (up to 106 A/m2). Current-voltage data modeling ...

متن کاملCharge transport in organic semiconductors.
Modern optoelectronic devices, such as light-emitting diodes, field-effect transistors and organic solar cells require well controlled motion of charges for their efficient operation. The understanding of the processes that determine charge transport is therefore of paramount importance for designing materials with improved structure-property relationships. Before discussing different regimes o...
متن کاملEvent Pileup in Charge-coupled Devices
The problem of event pileup in single-photonÈcounting CCD cameras (e.g., in the X-ray regime) is discussed, and a solution to the problem is proposed. The resulting pileup equation includes the e†ects of grade migration and presents itself as a nonlinear modiÐcation to the standard integral equation used by forward-folding spectral-Ðtting programs. The e†ectiveness of the model is demonstrated ...
