Lay summary

Le but de ce projet est de concevoir le détecteur inductif le plus sensible pour la spectroscopie a résonance de spin électronique (ESR) jamais réalisé. Notre approche sera basée sur l'intégration de tous les éléments importants pour la sensibilité d'un détecteur inductif ESR dans une seule puce de silicium ayant une superficie inférieure à 1 mm2. Nous visons à obtenir une sensibilité mieux que 10 million spins à 300 K (deux ordres de grandeur meilleure que les systèmes conventionnels) et mieux que 1000 spins à 4 K, avec une fréquence de fonctionnement d'environ 200 GHz.

Abstract

The aim of this project is to design the most sensitive inductive detector for electron spin resonance (ESR) spectroscopy ever realized. Our approach will be based on the integration of all sensitivity-wise significant elements of an ESR inductive detector into a single-chip having an area smaller than 1 mm2. We aim to obtain a spin sensitivity better than 107 spins/Hz1/2 at 300 K (two order of magnitude better than conventional systems) and better than 1000 spins/Hz1/2 at 4 K, with an operating frequency of about 200 GHz. In addition to the significantly improved sensitivity, we aim to demonstrate also the possibility to use the single-chip 200 GHz oscillator as efficient excitation source for dynamic nuclear polarization experiments as well as for low temperature measurements at the “quantum oscillator” limit.
