Current voltage characteristics and excess noise at the trap filling transition in polyacenes [PDF]

, 2018
Experiments in organic semiconductors (polyacenes) evidence a strong super quadratic increase of the current-voltage (I-V) characteristic at voltages in the transition region between linear (Ohmic) and quadratic (trap free space-charge-limited-current ...

Interplay between Intra- and Intermolecular Charge Transfer in the Optical Excitations of J-Aggregates

, 2019
In a first-principles study based on density functional theory and many-body perturbation theory, we address the interplay between intra- and intermolecular interactions in a J-aggregate formed by push-pull organic dyes by investigating its electronic ...

Nitrogen Monoxide Detection with Pentacene-Based Film Bulk Acoustic Resonators

Proceedings
Exposure to hazardous gases like NOx can have a negative effect on our health. High-performance sensors that are also able to sustain harsh environments are needed to control high levels of these contaminants, which in most cases, are generated by ...

Tuning the optoelectronic and charge transport properties of 2,5-di(pyrimidin-5-yl)thieno[3,2-b]thiophene by oligocene end cores substitution

Results in Physics, 2018
With the focus on tuning the charge transport and optoelectronic properties, various new derivatives were designed by substituting the oligocene moieties at end cores of 2,5-di(pyrimidin-5-yl)thieno[3,2-b]thiophene (Comp.1).

5,12‐TIPS‐Substitution of Tetracene: Effects on Redox Potentials and Cyclic Voltammetric Behavior in CH2Cl2 and THF1

Chemistry – A European Journal, EarlyView.
Tetracene and bis(tri(isopropyl)silylethynyl)tetracene (TIPS‐tetracene) exhibit characteristic similarities and differences in their electrochemical redox behavior depending on the base solvent of the electrolyte. Analysis of cyclic voltammograms allows the quantification of substituent and solvent effects and the calculation of an “electrochemical gap.

Distribution of localized states from fine analysis of electron spin resonance spectra of organic semiconductors: Physical meaning and methodology

, 2012
We develop an analytical method for the processing of electron spin resonance (ESR) spectra. The goal is to obtain the distributions of trapped carriers over both their degree of localization and their binding energy in semiconductor crystals or films ...

Ultrafast carrier dynamics in pentacene, functionalized pentacene, tetracene, and rubrene single crystals [PDF]

Applied Physics Letters, 2006
We measure the transient photoconductivity in pentacene, functionalized pentacene, tetracene, and rubrene single crystals using optical pump-terahertz probe techniques. In all of the samples studied, we observe subpicosecond charge photogeneration and a peak photoconductive response that increases as the temperature decreases from 297 down to 20K ...

An organic nanoparticle transistor behaving as a biological synapse

, 2009
Molecule-based devices are envisioned to complement silicon devices by providing new functions or already existing functions at a simpler process level and at a lower cost by virtue of their self-organization capabilities. Moreover, they are not bound to

Adsorption and electronic properties of pentacene on thin dielectric decoupling layers

Beilstein Journal of Nanotechnology, 2017
With the increasing use of thin dielectric decoupling layers to study the electronic properties of organic molecules on metal surfaces, comparative studies are needed in order to generalize findings and formulate practical rules.
