The recruited CDD researcher student will join the Terahertz (THz) Photonics Group of the Institute of Electronics in Microelectronics and Nanotechnology in Villeneuve d'Ascq (IEMN). Its mission will be to study samples by near-field microscopy in the mid-infrared (MIR). The candidate will perform certain stages of sample preparation and must master the use of the near-field microscope.


The main objective of the activity will be to use a near-field optical microscope in the MIR (in the range from 4 to 10 µm wavelength) for the characterization of different samples. The major part of the study will focus on the study of samples of chalcogenide glasses which have the property of being transparent in this MIR range unlike silica-based glasses. The near-field microscope is based on an atomic force microscope (AFM). The AFM probe is used as a scattering tip in order to carry out the optical image simultaneously with the measurement of the topography of the sample (scattering scanning near-field optical microscopy or s-SNOM technique).
The chalcogenide glass samples will be produced at the Institut des Sciences Chimiques de Rennes (ISCR) and these will be processed at the Laboratoire de Physico-Chimie de l'Atmosphère (LPCA). This treatment will consist of a photo-inscription carried out by a femtosecond laser, the material is then cut and polished to prepare the surface for microscopy. Deposits of other MIR transparent materials thin-films will be carried out in collaboration with other French laboratories for comparison. At the IEMN, the recruited cdd researcher will be involved in the preparation of the samples and the microscope, the use of the near field microscope and the interpretation of the results. Other characterization techniques can also be used to complete the SNOM.


The candidate must have a doctoral thesis specializing in micro - nanotechnology, if possible in the field of local probe microscopy (AFM, STM, SNOM, etc.). Advanced knowledge in optics or in the field of optical near-field microscopy (SNOM) would be a plus. Laser safety training would also be a plus.
Experience in clean room technology processes would also be welcome in order to perform some sample preparation.

Work Context

The candidate will join the THz Photonics group of IEMN which is specialized in THz and MIR components and devices. The group has expertise in simulation, characterization, technological manufacturing of devices and in near field microscopy in the THz and MIR fields. The microscope is located in the IEMN characterization platform.
The candidate will work within the framework of a consortium of the ANR COMI project grouping together the Laboratoire de Physico-Chemie de l'Atmosphère (LPCA), l'Institut des Sciences Chimiques de Rennes (ISCR), the MIRSENSE Company and the IEMN.
Specific training on security related to the clean room will be provided and the cdd researcher will be introduced to the techniques of using the various technological resources available.
