Journal ArticleDOI
Charge-transfer crystallites as molecular electrical dopants
H. Méndez,Georg Heimel,Stefanie Winkler,Stefanie Winkler,Johannes Frisch,Johannes Frisch,Andreas Opitz,Katrein Sauer,Berthold Wegner,Martin Oehzelt,Martin Oehzelt,Christian Röthel,Steffen Duhm,Daniel M. Többens,Norbert Koch,Norbert Koch,Norbert Koch,Ingo Salzmann +17 more
TL;DR: It is demonstrated that fundamentally different processes can occur in the two types of organic semiconductors instead of ground-state integer charge transfer as the basic mechanism of molecular electrical doping in both, conjugated polymers and oligomers.
Journal ArticleDOI
Doping of Organic Semiconductors: Impact of Dopant Strength and Electronic Coupling
H. Méndez,Georg Heimel,Andreas Opitz,Katrein Sauer,Patrick Barkowski,Martin Oehzelt,Martin Oehzelt,Junshi Soeda,Toshihiro Okamoto,Jun Takeya,Jean-Baptiste Arlin,Jean-Yves Balandier,Yves Geerts,Norbert Koch,Norbert Koch,Ingo Salzmann +15 more
TL;DR: By systematically varying the acceptor strength it was possible to discriminate the two models of molecular doping, suggesting strategies for the chemical design of more efficient molecular dopants.
Journal ArticleDOI
Transport gap of organic semiconductors in organic modified Schottky contacts
TL;DR: In this article, two different organic molecules with similar structure, 3,4,9,10-perylenetetetricarboxylic dianhydride (PTCDA) and N, N '-dimethyl-3, 4, 9, 10, 10-perYLenetetrarboxyl diimide (DiMe-PTCDI), were used for the modification of Ag Schottky contacts on sulphur passivated GaAs (S-GaAs).
Journal ArticleDOI

Marion Friedrich,G. Gavrila,Cameliu Himcinschi,Thorsten U. Kampen,A.Yu. Kobitski,H. Méndez,Georgeta Salvan,I. Cerrillo,Javier Méndez,Nicoleta Nicoara,A. M. Baró,Dietrich R. T. Zahn +11 more
TL;DR: In this article, the optical properties and the molecular orientation in thin films of 3,4,9,10perylenetetetricarboxylic dianhydride (PTCDA) and N,N � -dimethyl-3, 4, 9, 10perylENetetracarboxyl diimide (DiMePTCDI) were studied by means of variable angle spectroscopic ellipsometry (VASE), atomic force microscopy (AFM), near edge x-ray absorption fine structure (NEXAFS) spect
Journal ArticleDOI
Experimental study of charge transport mechanisms in a hybrid metal/organic/inorganic device
TL;DR: In this paper, the authors investigated the influence of thin film layers of the organic material Dimethyl-3,4,9,10-perylenetetetracarboxylic diimide DiMe-PTCDI on the electrical response of organic modified Ag/GaAs Schottky diodes.
