Sonochemical Synthesis of Silicon Hydride Polymers and Silicon Nanoparticles from Liquid Silanes
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 423, viii, 132, XVIII () = Dissertation, RWTH Aachen, 2018
The present thesis is concerned with the use of ultrasound for the treatment ofliquid silanes with the objective of fabricating solution-processable inks containingsilicon hydride polymers and silicon nanoparticles. Also demonstrated is the subsequentuse of the inks to deposit semiconducting hydrogenated amorphous silicon(a-Si:H) thin films and for fabricating passivation layers and thin-film photovoltaicdevices.The sonochemical effects of ultrasound on two lower silanes, namely cyclopentasilane(Si5H10) and trisilane (Si3H8) were studied.

Herstellung und Charakterisierung von Lithiumlanthanzirkonat-Funktionsschichten für Lithium-Festkörperbatterien
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 425, vii, 187 pp () = Dissertation, Univ. Bochum, 2017
The aim of this work is to produce a lithium ion conducting solid electrolyte as basicmaterial for application in new efficient energy storage such as solid state batteries. If theliquid electrolyte in lithium ion batteries (LIB) is replaced by a self-supported solidelectrolyte, safety, durability and energy density can be improved [...]

Femtosecond spin dynamics in magnetic multilayers employing high harmonics of laser radiation
Jülich : Forschungszentrum Jülich, Schriften des Forschungszentrums Jülich Reihe Schlüsseltechnologien / Key Technologies 70, VI, 121 S : Ill., graph. Darst () = Dissertation, Univ. Duisburg, 2013
This work explores laser-induced, element-selective, femtosecond spin dynamics in ferromagneticlayered structures. As a model system, interlayer exchange coupled Fe/Ru/Nilayers were investigated in time- and element-selective, magneto-optical measurements atthe 3p absorption edges of Fe (54 eV) and Ni (67 eV) in the transversal magneto-opticalKerr effect (T-MOKE) geometry [...]

Magnetic oxide heterostructures : EuO on cubic oxides and on silicon
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Schlüsseltechnologien / Key Technologies 69, 153 S : zahlr. Ill. u. graph. Darst () = Dissertation, Univ. Duisburg, 2013
In the thesis at hand, we explore fundamental properties of ultrathin europium oxide (EuO) films.EuO is a model system of a localized 4f Heisenberg ferromagnet, in which the ferromagnetic coupling– provided a high crystalline quality – can be tuned by biaxial lattice strain. Moreover, the magneticoxide EuO is perfectly suited as a spin-functional tunnel contact for silicon spintronics [...]
