The Laboratory of Science of Processes and Materials (LSPM) is a French CNRS research unit connected to the University of Paris 13 which is focused on developing both theoretical and applied research in the fields of Material Science and Process Engineering. The activities are organized around 3 research axis: the development of materials fabrication and transformation processes, the study of their structural characteristics and properties, and their integration into systems and devices. In particular one of LSPM’s research group (PEMA - Fabrication Processes of Advanced Materials) has been involved for more than 20 years in the synthesis of diamond films by the Plasma Assisted Chemical Vapour Deposition technique. This activity deals with every aspects of the material fabrication, from the study of plasma chemistry by combined spectroscopic and modeling analysis, the design of optimized growth reactors, the synthesis of nano, poly and single crystal diamond films and to some extend their integration into a working device
LSPM-CNRS is involved in the material synthesis workpackage (WP 2). The growth of high quality and purity single crystal films will be optimized by PACVD on non-conventional orientations such as (111) and (113) using an isotopically controlled gas composition. This should allow substantial control over the orientation, stability and spin bath environment of NV luminescent centres towards their use in efficient magnetometers. In addition strategies will be developed in order to spatially localize such NV defects in the diamond matrix.
