Journal ArticleDOI
Role of Oxygen Vacancies in Cr‐Doped SrTiO3 for Resistance‐Change Memory
Markus Janousch,Gerhard Ingmar Meijer,Urs Staub,Bernard Delley,Siegfried Karg,Björn Pererik Andreasson +5 more
TL;DR: In this article, a high density of oxygen vacancies has been found in an experiment to determine the path of electrical conduction in Cr-doped SrTiO3 memory cells, leading to a statistically homogeneous distribution of charge carriers within the path.
Journal ArticleDOI
Polymeric anodes for improved polymer light-emitting diode performance
TL;DR: In this article, the anodes were doped with a variety of polymer and monomer-based acids and cast from either water or organic solvents to determine the effect of the dopant and solvent on the hole-injection properties.
Journal ArticleDOI
Realization of a silicon nanowire vertical surround-gate field-effect transistor.
TL;DR: A generic process for fabricating a vertical surround-gate field-effect transistor (VS-FET) based on epitaxially grown nanowires is described, and a first electrical characterization proving the feasibility of the process developed and the basic functionality of this device is presented.
Journal ArticleDOI
Thermally Stable Blue-Light-Emitting Copolymers of Poly(alkylfluorene)
M. Kreyenschmidt,Gerrit Klaerner,T. Fuhrer,J. Ashenhurst,Siegfried Karg,W. D. Chen,V. Y. Lee,John Campbell Scott,Robert D. Miller +8 more
TL;DR: In this article, a variety of high molecular weight, thermally stable, blue-light-emitting random copolymers of 9,9-di-n-hexylfluorene by nickel(0)-mediated polymerization are presented.
Journal ArticleDOI
Ambipolar light-emitting organic field-effect transistor
Constance Rost,Siegfried Karg,Walter Riess,Maria Antonietta Loi,Mauro Murgia,Michele Muccini +5 more
TL;DR: In this article, a light-emitting organic field effect transistor (OFET) with pronounced ambipolar current characteristics is demonstrated, where the light intensity is controlled by both the drain-source voltage VDS and the gate voltage VG.
