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

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

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, ...

Controlling domain wall motion in ferroelectric thin films

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl

Domain walls in ferroic materials have attracted significant interest in recent years, in particular because of the unique properties that can be found in their vicinity(1-3). However, to fully harness their potential as nanoscale functional entities(4,5), ...

Effect of Heat Current on Magnetization Dynamics in Magnetic Insulators and Nanostructures

Francesco Antonio Vetrò

The term "spin caloritronics" defines a novel branch of spintronics that focuses on the interplay between electron spins with heat currents. In the frame of this research area, this thesis is aimed at investigating the effect of a heat current on magnetiza ...

Cell Shape Dynamics Reveal Balance of Elasticity and Contractility in Peripheral Arcs

Jean-Jacques Meister, Alexander Verkhovskiy, Chiara Gabella, Benoît Vianay, Céline Jeanne Labouesse

The mechanical interaction between adherent cells and their substrate relies on the formation of adhesion sites and on the stabilization of contractile acto-myosin bundles, or stress fibers. The shape of the cell and the orientation of these fibers can be ...

Development of a system for part quality prediction and process parameters adjustment in wire electrical discharge machining

Olcay Akten

In the past decades, wire electric discharge machining (W-EDM) has undergone a number of techno-logical developments aimed at improving its process performance. Still the current practice of W-EDM is not defect-free and results in a number of surface relat ...

Electrical contacts to single nanowires: a scalable method allowing multiple devices on a chip. Application to a single nanowire radial p-i-n junction

Anna Fontcuberta i Morral, Carlo Colombo, Martin Heiss, Anna Dalmau Mallorquí, Pierre Loïc Blanc

Semiconductor nanowires are currently at the forefront of research in the areas of nanoelectronics and energy conversion. In all these studies, realising electrical contacts and statistically relevant measurements is a key issue. We propose a method that e ...

DC Breakdown in gases for complex geometries from high vacuum to atmospheric pressure

Ralph Schnyder

This thesis presents an experimental investigation and a numerical simulation of breakdown in a ring assembly. Previous works are mostly limited to breakdown in simple geometries such as parallel plates or pin-to-plate. Here we discuss the effect of more c ...
