„CVD diamond a novel miraculous material for sensors fabrication ?-Diamond activities at LCD CEA-LIST”
prelegent: dr Michał Pomorski (CEA Saclay)
Streszczenie: Diamond (from ancient Greek ADAMAS = unbreakable or indestructible, also untamable) known from centauries as a gemstone (often associated with many different beliefs) since XIX employed in cutting, polishing and drilling industry but barely used in science. For a long time being untamable in terms of impurities, in the early 2000s advances in Chemical Vapor Deposition (CVD) technique allowed growth of a novel diamond - almost defect free material. The CVD diamond - a large band-gap semiconductor - becomes today a commercial available material widely used for fabrication of sensors and electronic devices with outstanding properties. Since 1994, initiated by the needs of the nuclear industry and physics, Diamond Sensors Laboratory of CEA-LIST (former Detectors Technology Laboratory) develops radiation detection devices with diamond. The laboratory has greatly diversified in the early 2000s and has acquired new areas of expertise including security, industry, chemistry and biology. Nowadays, the laboratory is based on a highly multidisciplinary team of about 20 researchers - physicists, materials and surfaces scientist, sensors experts, chemists, electrochemists, biologists and engineers. A brief introduction to the major research activities of the laboratory will be presented, including: Micro Electro-Mechanical Systems (MEMS), diamond nanoparticles for biomedical applications, Surface Acoustic Wave (SAW) chemical sensors, and boron-doped diamond electrodes for biomedical implants and electrochemistry. Particular attention will be given to the diamond radiation sensors including: ultra-thin membranes for particles detection, 3D detectors for High Energy Physics (HEP) and X-ray beam monitors for modern light sources.
