Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for contactless 360 degrees absolute angle encoding. The sensing device consists of a narrow n-well ring with a chain of 64 contacts equally distributed along the ring. It is ...

The exponential localization of Wannier functions in two or three dimensions is proven for all insulators that display time-reversal symmetry, settling a long-standing conjecture. Our proof relies on the equivalence between the existence of analytic quasi- ...
Ever since the novel quantum Hall effect in bilayer graphene was discovered, and explained by a Berry phase of 2 pi [K. S. Novoselov et al., Nat. Phys. 2, 177 (2006)], it has been widely accepted that the low-energy electronic wave function in this system ...
Contactless current measurement based on Hall-effect sensors can be performed in either closed-or open-loop configuration. In this paper an open-loop sensor system with a current-mode output is described. The system measures the magnetic field induced arou ...

We have studied experimentally the nonequilibrium currents (NECs) induced by sweeping either the magnetic field B or the carrier density nS of a two-dimensional electron system (2DES). The gated 2DES resided in a modulation-doped GaAs/AlxGa1−xAs heterostru ...

In order to provide the information on their Hall voltage, sensitivity and drift with temperature, a new simpler lumped circuit model for the evaluation of various Hall Effect sensors has been developed. In this sense, the finite element model associated c ...
We investigated the performance of Hall sensors with different Co-C ratios, deposited directly in nanostructured form, using Co-2(CO)(8) gas molecules, by focused-electron or ion-beam-induced deposition. Due to the enhanced intergrain scattering in these g ...
The first commercially available teslameter with a fully integrated three-axis Hall probe is described. The Hall probe chip contains horizontal and vertical Hall elements, analog electronics, and a synchronization circuit. A horizontal Hall element measure ...
