Job Description
Thesis Subject
Context and state-of-the-art
Among the various solid-state material systems that are being considered for quantum sensing, colour centres in diamond are arguably one of the most promising and studied. The growing interest that surrounds this material essentially stems from the outstanding optical and spin properties of the nitrogen-vacancy (NV) colour centre. In many cases, the precise positioning of NV centres both in-depth and in-plane is of importance for integrating them into devices or for improving their performance by controlling their distance at the nanometre scale.
Novelty and objectives
This PhD project aims at tackling the challenge of precisely positioning NV centres in order to engineer diamond material that provides an ideal platform for quantum sensing applications. Ultra-thin (below 100 nm) diamond layers in which NV centres are intentionally doped will be deposited using a newly developed “low-power” chemical vapour deposition (CVD) reactor. Controlling the substrate material surface preparation, the growth conditions (growth rate, temperature etc.) and the quantum properties of NV centres (density, coherence time, spatial positioning) will be key to achieve high quality diamond films with optimal performance. This approach can be combined by the local implantation of nitrogen using a focused ion beam that is already well established in our research group.
Your Work Environment
The selected student will join a dynamic scientific environment at IRCP (Université Paris Sciences et Lettres), in the Crystal and Quantum State Dynamics research axis (part of the Materials for Photonics and Opto-Electronics group) benefiting from expertise in material design, fabrication, and spectroscopic characterization of solid-state quantum materials. The results achieved will contribute to advancing the next generation of engineered diamond materials, which are increasingly relevant for advanced sensing applications.
Constraints and risks
The candidate will be expected to have good experimental and communication skills. He/she will have a solid background in Materials Science and, if possible, knowledge of elaboration techniques and chemical and structural characterisation of films. Expertise in analysis of colour centres in diamond or diamond growth by CVD would also be a great asset, although not mandatory.
