Microwave plasma-assisted reactive HiPIMS of InN films: Plasma environment and material characterisation

Aïcha Hessler-Wyser, Johann Michler, Jonathan Emanuel Thomet, Caroline Hain, Thomas Nelis

This work focuses on the low temperature fabrication process of InN thin films via microwave plasma-assisted reactive high power impulse magnetron sputtering (MAR-HiPIMS). The influence of microwave plasma on the HiPIMS discharge process at various nitroge ...

Two-dimensional atomically bridged nanoporous silicate-based membranes for gas separation

Mostapha Dakhchoune

The synthesis of molecular-sieving two-dimensional zeolitic membranes by the assembly of crystalline building blocks without resorting to the secondary growth process is highly desirable. The precise pore size for molecular sieving, ultrathin thickness, an ...

Identification of a Dps contamination in Mitomycin-C–induced expression of Colicin Ia

Henning Paul-Julius Stahlberg

Colicins are bacterial toxins targeting Gram-negative bacteria, including E. coli and related Enterobacteriaceae strains. Some colicins form ion-gated pores in the inner membrane of attacked bacteria that are lethal to their target. Colicin Ia was the firs ...

Catalyzing Bond-Dissociation in Graphene via Alkali-Iodide Molecules

Klaus Kern, Stephan Rauschenbach, Sabine Abb, Sven Alexander Szilagyi, Hannah Julia Ochner

Atomic design of a 2D-material such as graphene can be substantially influenced by etching, deliberately induced in a transmission electron microscope. It is achieved primarily by overcoming the threshold energy for defect formation by controlling the kine ...

Longitudinal and transverse modulation of electron wave function with light, and its application to electron microscopy

Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Enrico Pomarico, Gabriele Berruto, Ido Kaminer

Conventional electron microscopy operates with flat electron wave fronts. Employing attenuative or electrostatic phase plates allows transversally modulating the wave front, enhancing cross-sections of particular scattering channels. Utilization of light f ...

Island formation of Er(trensal) single-ion magnets on graphene observed on the micrometer scale

Christian Wäckerlin, Jan Gui-Hyon Dreiser

We have studied the morphology of Er(trensal) single-ion molecular magnets adsorbed on graphene/Ru(0001) using X-ray photoemission electron microscopy (X-PEEM). By exploiting the elemental contrast at the erbium M-5 edge we observe the formation of molecul ...

Ultrafast Momentum-Resolved Free-Electron Probing of Optically Pumped Plasmon Thermal Dynamics

Fabrizio Carbone, Vahagn Mkhitaryan

Current advances in ultrafast electron microscopy make it possible to combine optical pumping of a nanostructure and electron beam probing with sub-Angstrom and femtosecond spatiotemporal resolution. We present a theory predicting that this technique can r ...
