DEEP2D both targets new basic knowledge on nanomaterials and its envisioned breakthrough for nanoelectronics and optoelectronics. It belongs to worldwide efforts devoted to basic understanding of novel nanomaterials, and of their implementation into alternative nanoelectronics technologies. Our multidisciplinary approach, both experimental and theoretical, will unveil a large panel of ground breaking knowledge in several fields among which nanomaterials and surface physics, optoelectronics and nanoelectronics. We address defect properties unexplored so far, while pursuing the careful understanding of their structural, electronic, and optoelectronic properties by the use of a unique set of top-notched characterization tools and theoretical modeling never gather so far to study these systems.
Our philosophy is to exploit the specific properties of 2D material and their defect engineering to design devices with multiple functionalities that cannot be obtained using conventional 2D materials thin film technologies. Here the joint exploitation of the defect engineering, electronic and photo-physical properties of the nanomaterials will allow us i/ to propose new device concepts contributing to the rising fields of 2D materials, optoelectronics, and ii/ to achieve device performances beyond the state of the art.
The Deep2D project gathers French experts in the fields of 2D materials, optical and electronic properties and transport, van der Waals epitaxy, and advanced characterization tools (STM/STS, PL/Raman, XPS/ARPES). Our consortium is composed of four very complementary partners, which bring all the necessary skills to the success of the project, including nanomaterial synthesis (PMC, IEMN, C2N and LSI), material characterization (PMC, C2N, IEMN), device fabrication (IEMN and C2N), electric and optoelectronic (PMC) transport measurements and DFT calculations (LSI). The four Partners share the interest for, and have strong experience in collaborative and multidisciplinary research as the one followed in DEEP2D project.
