A word from the Director

The Laboratory of Physics of Interfaces and Thin Films (LPICM) is jointly supported by both the CNRS and the École polytechnique. The LPICM was established in 1986 and become a recognized research unit (UMR7647) in 1997. Today, the laboratory is associated with the Institute for Engineering and Systems Sciences (INSIS) while it also has a partnership with the Ins&tute of Physics (INP) and the Institute of Chemistry (INC).

Since its founding, the LPICM has considerably evolved to become a multidisciplinary laboratory where fundamental research on materials science, chemistry, optics and electronics is carried out. Building on this foundation, we design and develop new electrical and optoelectronic devices, covering the elds of solar energy harvesting and storage, innovative sensors based on nanomaterials, and large-area electronic devices. Our research strategy is based on a bobom-up approach, wherein the optimization of materials and processes relies on in-situ real- time diagnostic techniques developed in- house, backed up with ex-situ characterization and numerical modeling. In particular the laboratory has developed innovative optical characterization techniques such as Mueller polarimetry, which we apply to thin lms for microelectronics as well as to biomedical applications such as the diagnosis of cancer tissues. Tip Enhanced Raman Spectroscopy (TERS) has also been recently developed to characterize nano-objects (nanowires, nanotubes, and graphene) and successfully transferred to industry.
