The digitalization of our world is proceeding with every new technical product placed on the market. By making them smarter, e.g. linking them together and equipping them with sensors, a vast mass of data is collected. Processing and storing this informati ...
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 ...
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 ...
Nanowire (NW) semiconductors are interesting devices for being used as sensors. Such NWs are doped silicon channels with electrical contacts at both ends, which is a kind of the so-called junctionless (JL) device. However, in contrast with the state-of-the ...

In spin caloritronics, ferromagnetic samples subject to relatively large in-plane temperature gradients T have turned out to be extremely interesting. We report on a preparation technique that allows us to create freely suspended permalloy/Pt hybrid struct ...
We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...
The present invention relates to a solar cell comprising a semiconductor wafer (1), an emitter formed by at least one emitter region (20) which comprises at least a first layer (3) of a first conductivity type and a first contact layer (4) allowing a carri ...
The present invention relates to a device including a ferroic material having a ferroelectric order parameter and including at least two domains, as well as a first and second electrode in electrical contact with the ferroic material. The device is configu ...
Spin caloritronics, i.e., the addition of thermal effects to the electrical and magnetic properties of nanostructures, has recently seen a rapid development. It has been predicted that a heat current can exert a spin torque on the magnetization in a nanost ...
Electrical contacts between nanoengineered systems are expected to constitute the basic building blocks of future nanoscale electronics. However, the accurate characterization and understanding of electrical contacts at the nanoscale is an experimentally c ...
