Lay Summary (English)

Lead
Lay summary
The aim of this project is to design the most sensitive inductive detectors for electron spin resonance spectroscopy ever realized. Additionally, we intend to demonstrate that, thanks to the high spin sensitivity, spatial resolution, and versatility of the realized devices, spectroscopic and imaging experiment at the nanometer scale, hitherto well beyond the sensitivity limitations of state-of-the-art conventional systems, will become feasible. Our approach will be based on the integration of the sensitivity-wise significant elements into a single-chip having an area smaller than 1 mm^2. We aim to obtain spins sensitivity better than 10^8 spins/Hz^1/2 at 300 K  and better than 1000 spins/Hz^1/2 at 4 K, with operating frequencies from 10 GHz to 100 GHz. The devices will be specifically conceived for samples having dimensions of 100 μm and smaller, with the aim of achieving spatial resolutions better than 100 nm.

Abstract

The aim of this project is to design the most sensitive inductive detectors for electron spin resonance spectroscopy ever realized. Additionally, we intend to demonstrate that, thanks to the high spin sensitivity, spatial resolution, and versatility of the realized devices, spectroscopic and imaging experiment at the nanometer scale, hitherto well beyond the sensitivity limitations of state-of-the-art conventional systems, will become feasible. Our approach will be based on the integration of the sensitivity-wise significant elements into a single-chip having an area smaller than 1 mm2. We aim to obtain spins sensitivity better than 108 spins/Hz^1/2 at 300 K (two order of magnitude better than conventional systems) and better than 1000 spins/Hz^1/2 at 4 K, with operating frequencies from 10 GHz to 100 GHz. The devices will be specifically conceived for samples having dimensions of 100 µm and smaller, with the aim of achieving spatial resolutions better than 100 nm.
