A unified description of ordering in HCP Mg-RE alloys

High throughput first-principles calculations were employed to unravel the thermodynamic stability of two sets of hierarchical phases, β′′′P and β′′′S, in Mg-RE (rare-earth) alloys. The β′′′P orderings (with compositions greater than xRE=0.125) are predict ...

Effect of Hf Metal Layer on the Switching Characteristic of HfOX-based Resistive Random Access Memory

Elmira Shahrabi, Yusuf Leblebici, Jury Sandrini, Behnoush Attarimashalkoubeh, Marios Barlas

In this study, we propose the insertion of an ultrathin Hf layer at the interface between TiN (top electrode) and HfOX (electrolyte), and then studied its effect on the device electrical properties. In order to obtain the desired switching characteristics, ...

Fine structuration of low-temperature co-fired ceramic (LTCC) microreactors

Albert Renken, Paul Muralt, Lioubov Kiwi, Thomas Maeder, Bo Jiang, Julien Haber

The development of microreactors that operate under harsh conditions is always of great interest for many applications. Here we present a microfabrication process based on low-temperature co-fired ceramic (LTCC) technology for producing microreactors which ...

Self-aligned normally-off metal-oxide-semiconductor n(++)GaN/InAlN/GaN high electron mobility transistors

Nicolas Grandjean, Jean-François Carlin

Self-aligned normally-off n(++)GaN/InAlN/AlN/GaN MOS HEMTs with a recessed gate show scalable threshold voltage between 1.3 to 3.7V, which increases with the gate oxide thickness. Al2O3 or HfO2 gate insulators were grown by ALD at 100 degrees C so that one ...

Quantifying residual hydrogen adsorption in low-temperature STMs

Harald Brune, François Patthey, Donat Fabian Natterer

We report on low-temperature scanning tunneling microscopy observations demonstrating that individual Ti atoms on hexagonal boron nitride dissociate and adsorb hydrogen without measurable reaction barrier. The clean and hydrogenated states of the adatoms a ...

Processing and Consolidation of TaC/HfC Based Composites Using MoSi2 and Carbon Nanotubes

Mehdi Mazaheri

Tantalum and hafnium carbides are classified as Ultra High Temperature Ceramics (UHTC) because of their extreme melting temperatures (above 3900 degrees C). Therefore, these materials can safely operate in the range of temperature that any other materials ...

Highly efficient bacteria inactivation and phenol degradation by visible light irradiated iodine doped TiO2

László Forró, Andrzej Sienkiewicz, Klara Hernadi

In this study visible light active iodine doped titanium dioxide samples prepared by sol-gel method were investigated. Photocatalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray fluorescence spectroscopy (XF ...

Dispersion engineering of thick high-Q silicon nitride ring-resonators via atomic layer deposition

Tobias Kippenberg, Victor Brasch, Tobias Herr

We demonstrate dispersion engineering of integrated silicon nitride based ring resonators through conformal coating with hafnium dioxide deposited on top of the structures via atomic layer deposition. Both, magnitude and bandwidth of anomalous dispersion c ...
