Optimizing Atomic Layer Deposition Processes with Nanowire-Assisted TEM Analysis
Johann Michler, Ivo Utke, Xavier Maeder
Atomic layer deposition (ALD) is one of the premier methods to synthesize ultra-thin materials on complex surfaces. The technique allows for precise control of the thickness down to single atomic layers, while at the same time providing uniform coverage ev ...
Hoboken2024Nanostructure and Optical Property Tailoring of Zinc Tin Nitride Thin Films through Phenomenological Decoupling: A Pathway to Enhanced Control
Aïcha Hessler-Wyser, Johann Michler, Amit Sharma, Caroline Hain, Daniele Casari, Thomas Nelis
This work addresses the need for precise control of thin film sputtering processes to enable thin film material tailoring on the example of zinc tin nitride (ZTN) thin films deposited via microwave plasma-assisted high power reactive magnetron sputtering ( ...
Amer Chemical Soc2024Crystalline or amorphous? A critical evaluation of phenomenological phase selection rules
In this work, we reviewed the available phase selection rules comprising atomic size and topological aspects, entropies, enthalpies, melting points, valence and itinerant electron concentrations, as well as electronegativity, and validated them using a car ...
ELSEVIER SCI LTD2023Atomic scale volume and grain boundary diffusion elucidated by in situ STEM
Johann Michler, Xavier Maeder, Laszlo Pethö, Amit Sharma
Diffusion is one of the most important phenomena studied in science ranging from physics to biology and, in abstract form, even in social sciences. In the field of materials science, diffusion in crystalline solids is of particular interest as it plays a p ...
Berlin2023From pulsed-DCMS and HiPIMS to microwave plasma-assisted sputtering: Their influence on the properties of diamond-like carbon films
Aïcha Hessler-Wyser, Johann Michler, Caroline Hain, David Brown, Thomas Nelis
The fabrication of high-hardness non-hydrogenated diamond-like carbon (DLC) via standard magnetron sputtering (MS) is often hindered by the low sputtering yields and ionisation rates of carbon, therefore investigations into pulsed alternatives of MS, else ...
ELSEVIER SCIENCE SA2022Evolution of deformation twinning mechanisms in magnesium from low to high strain rates
Roland Logé, Cyril Cayron, Johann Michler, Xavier Maeder, Amit Sharma, Nicolò Maria Della Ventura, Manish Jain
We present a systematic investigation of {10 (1) over bar2} extension twinning mechanism in single crystal magnesium micropillars deformed over seven orders of magnitude of strain rate, from 10(-4) to 500 s(-1), revealing how the accommodation of newly for ...
ELSEVIER SCI LTD2022Microwave 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 ...
ELSEVIER SCIENCE SA2022Microtensile failure mechanisms in lamellar bone: Influence of fibrillar orientation, specimen size and hydration
Johann Michler, Daniele Casari, Tatiana Kochetkova
A mechanistic understanding of bone fracture is indispensable for developing improved fracture risk assessment in clinics. Since bone is a hierarchically structured material, gaining such knowledge requires analysis at multiple length scales. Here, the ten ...
ELSEVIER SCI LTD2021{10(1)over-bar2} twinning mechanism during in situ micro-tensile loading of pure Mg: Role of basal slip and twin-twin interactions
Roland Logé, Johann Michler, Xavier Maeder, Amit Sharma, Daniele Casari, Nicolò Maria Della Ventura
An SEM in situ uniaxial tensile testing setup allowing HR-EBSD acquisition during deformation was used to study the extension twinning mechanism in magnesium(Mg) at the micron scale. Structures were fabricated with two different crystal orientations, respe ...
ELSEVIER SCI LTD2021Mechanical Properties of Soft Biological Membranes for Organ-on-a-Chip Assessed by Bulge Test and AFM
Georg Fantner, Johann Michler, Veronika Cencen
Advanced in vitro models called “organ-on-a-chip” can mimic the specific cellular environment found in various tissues. Many of these models include a thin, sometimes flexible, membrane aimed at mimicking the extracellular matrix (ECM) scaffold of in vivo ...
