Missions

This project aims to meet the challenge of precise positioning of NV centers in synthetic diamond, in order to develop an optimal diamond platform for the implementation of quantum sensors. It is based on a collaborative ANR project (“Trampoline”) coordinated by the LSPM and bringing together the expertise of our team at IRCP, with LPENS and the Swiss company Q-Nami. The approach will involve implanting colored centers in diamond using a focused ion beam (FIB) whose unique design enables it to operate under a wide range of conditions and at high temperatures. The properties of the NV centers created will be assessed by photoluminescence and optically detected magnetic resonance (ODMR). The properties of the NV centers will also be enhanced by optimized post-processing using thermal annealing and plasma, and nanostructures will be generated from this material. Finally, chemical vapor deposition of encapsulating diamond layers will be carried out using a reactor currently being developed at IRCP.

Work Context

IRCP (Institut de Recherche de Chimie Paris) is one of the leading chemistry laboratories in the Paris region. Our team (MPOE) is expert in the design, growth, characterization and modeling of massive and nanometric crystals, as well as thin films. Two main material systems for photonics and quantum technologies are currently being studied in our laboratory: rare-earth ion-doped oxides and diamond films containing colored centers. This post-doctoral project falls more specifically within this second axis. We have recently developed a specific platform aimed at improving the properties of materials for quantum applications, using various post-treatments. These include ion beam irradiation at different temperatures and fluences, surface modification by plasma etching, diamond re-growth by CVD and rapid thermal annealing. The candidate will be part of a team of 5 permanent researchers and around ten PhD and post-doctoral students, and will have access to all development and characterization equipment.
