Job Description
Thesis Subject
Quantum sensing technologies powered by solid-state spin defects have already shown a huge potential for covering the growing need for high-precision sensors, both for basic science and for industrial applications. State-of-the-art quantum sensing methods rely on spin defects hosted in three-dimensional (3D) materials which are facing several obstacles including (i) a limited sensitivity resulting from the dim proximity that can be achieved between the quantum sensor and the target sample, and (ii) the inability to engineer ultrathin and flexible quantum sensors that could be easily transferred onto the samples to be probed or integrated into complex multifunctional devices. The objective of this research project is to overcome these limitations through the design of a flexible, quantum sensing foil based on an atomically-thin two-dimensional (2D) material.
Our approach consists in using optically-active spin defects hosted in 2D hexagonal boron nitride (hBN), a widebandgap material which is a key building block of van der Waals heterostructures. More precisely, the work will be focused on the study of the spin and optical properties of the boron vacancy (VB) defect in hBN, in order to assess its potential for quantum sensing applications, with a focus on magnetic field detection. The objective of the PhD will be to analyze the performances of ultrathin hBN flakes (down to the monolayer limit) doped with VB centers for quantitative magnetic field imaging at cryogenic temperature (4K). The 2D quantum sensor will then be integrated into van der Waals heterostructures in order to probe, in situ, the physics occurring at the interfaces between atomically thin 2D materials assembled in vertical stacks, with a focus on 2D magnets and 2D superconductors.
Your Work Environment
The PhD thesis will be carried out within the Solid-state Quantum Technologies team (S2QT – https://solidstatequantumtech-l2c.fr/) of the Charles Coulomb Laboratory in Montpellier. The doctoral work will be supervised by Vincent Jacques through daily discussions, weekly meetings to assess scientific progress, and the preparation of interim reports.
