TL;DR: It is shown that continuous band energy tuning is indeed possible by varying the blend ratios of certain organic phthalocyanines and their fluorinated or chlorinated derivatives, and photoelectron spectroscopy confirms that the ionization energies of crystalline organic semiconductors can be continuously tuned over a wide range by blending them with their halogenated derivatives.
Journal ArticleDOI
Contact Doping for Vertical Organic Field‐Effect Transistors
TL;DR: In this article, the performance of p-type VOFETs with pentacene as an active material can be significantly enhanced by the addition of the common p-dopant C60F36 as a thin injection layer underneath the source electrode, resulting in an increase of On-state current and On/Off ratio by one order of magnitude.
Journal ArticleDOI
High‐Performance Vertical Organic Transistors
TL;DR: In this paper, high performance vertical organic transistors comprising pentacene for p-type operation and C60 for n-type operations are presented, disclosing a remarkable transistor operation with a behavior limited by injection of charge carriers.
Journal ArticleDOI
Vertical organic transistors.
TL;DR: Several different approaches have been proposed in literature, which show high output currents, low operation voltages, and comparatively high speed even without sub-μm structuring technologies, and in this review, these different approaches are compared and recent progress is highlighted.
Journal ArticleDOI
Materials Meets Concepts in Molecule-Based Electronics
Frank Ortmann,K. Sebastian Radke,Alrun A. Günther,Daniel Kasemann,Karl Leo,Karl Leo,Gianaurelio Cuniberti +6 more
TL;DR: In this paper, molecular materials are highlighted as an important topic in the diverse field of condensed matter physics, with focus on their particular electronic and transport properties, including the accurate description of electron-phonon coupling.
