Electronic and vibrational properties of diamondoid derivatives, graphite, and carbon nanotubes

Tyborski, Christoph (2018)

In this work, we present an analysis of vibrational and electronic properties of diamondoids, graphene, multilayer graphene, graphite, and carbon nanotubes. The realized studies are based on optical spectroscopy, such as Raman spectroscopy, photo luminescence, photo luminescence excitation, and absorption spectroscopy, but also on in-depth model calculations. Although the analyzed material syst...

Growth and characterization of antimony-based quantum dots in GaP matrix for nanomemories

Sala, Elisa Maddalena (2018)

Self-assembled Quantum Dots (QDs) have recently attracted great attention for enabling a novel type of non-volatile electronic nanomemory, the QD-Flash. Such a memory architecture represents the ultimate memory cell, exhibiting endurance and fast access times (~ns). To ensure non-volatile operation, the storage time for carriers has to be of the order of 10 years (or longer) at room temperature...

Magnetic properties of rare earth zirconate pyrochlores

Xu, Jianhui (2017)

Diese Dissertation behandelt experimentelle Untersuchungen an drei magnetischen Pyrochloren, Nd2Zr2O7, Sm2Zr2O7 and Gd2Zr2O7. Es wurden einkristalline und pulverförmige Proben hergestellt wobei die zwei erstgenannten Substanzen in der Pyrochlor Struktur kristallisieren, während Gd2Zr2O7 einige Platzwechsel-Defekte von Gd/Zr aufweist. Alle Verbindungen zeigen in den makroskopischen Eigenschaften...

Few-layer antimonene by liquid-phase exfoliation

Gibaja, Carlos ; Rodriguez-San-Miguel, David ; Ares, Pablo ; Gómez-Herrero, Julio ; Varela, Maria ; Gillen, Roland ; Maultzsch, Janina ; Hauke, Frank ; Hirsch, Andreas ; Abellán, Gonzalo ; Zamora, Félix (2016)

We report on a fast and simple method to produce highly stable isopropanol/water (4: 1) suspensions of few-layer antimonene by liquid-phase exfoliation of antimony crystals in a process that is assisted by sonication but does not require the addition of any surfactant. This straightforward method generates dispersions of few-layer antimonene suitable for on-surface isolation. Analysis by atomic...

Blind testing of cross-linking/mass spectrometry hybrid methods in CASP11

Schneider, Michael ; Belsom, Adam ; Rappsilber, Juri ; Brock, Oliver (2016)

Hybrid approaches combine computational methods with experimental data. The information contained in the experimental data can be leveraged to probe the structure of proteins otherwise elusive to computational methods. Compared with computational methods, the structures produced by hybrid methods exhibit some degree of experimental validation. In spite of these advantages, most hybrid methods h...
