M2 internship: Research in nonlinear optics applied to the characterization of neuromorphic electronic devices - 6 months
France | Nov. 8, 2026
Company: Institut Mines-Télécom
Country: France
Type: Onsite
Employment: Student college
Description: Mines Saint-Etienne is a school of the Institut Mines-Télécom (IMT), the leading public group of engineering and management schools in France. The IMT is an EPSCP (large establishment) under the supervision of the Ministry of the Economy, Finance and Industrial and Digital Sovereignty. The École Nationale Supérieure des Mines de Saint-Étienne (Mines Saint-Etienne) is responsible for training, research and innovation, transfer to industry and culture missions. scientific, technical and industrial. Mines Saint-Etienne represents: 2,400 engineering students and researchers in training, 480 staff (150 Researchers and Teacher-researchers), a consolidated budget of €46 million, 3 campuses dedicated to industry in Saint-Etienne and Lyon (AURA region), microelectronics and connected objects in Gardanne (Aix-Marseille Provence metropolis, SOUTH region) and health engineering in Saint-Etienne; 6 research units; 5 training and research centers; a leading technical and industrial scientific culture center in France "La Rotonde" (> 50,000 visitors / year). ultra-flexible, conformable and implantable organic electronics incorporating artificial intelligence promise to revolutionize the real-time monitoring and treatment of chronic diseases [1]. Such systems could be based on organic electrochemical transistors (OECTs), exploiting polymer mixed ion-electron conductors (PMIECs) as active layers. Indeed, PMIECs have emerged as an excellent hardware platform for interfacing biology with conventional electronics; identified as the field of “organic or plastic bioelectronics”. The OECT is considered the key element to achieve such an interface [2]. Its efficiency is evaluated according to figures of merit (FoMs) such as i) transconductance (gm), and/or ii) switching times (ionic vs. electronic) in the device. Beyond transduction applications, in the short term, OECT is also interesting for creating emerging applications in bioelectronic neuromorphic circuits [3]. notably an asymmetry of transistor switching times during doping sequences (i.e. “ON”) vs. dedoping (i.e. “OFF”) in the OECT channel. in-situ & operando characterization tools making it possible to quantify and map the electronic and electrochemical transduction parameters in the OECT channel prove to be essential for understanding the current performance limitations of PMIECs and/or for constructing optimal PMIECs in such neuromorphic circuits. In this scientific context, the intern will develop a new nonlinear optical spectroscopy and instrumentation measurement, called time-resolved second harmonic generation microscopy, in order to record the spatio-temporal movement of charged species, ions and electrons (or holes), and thus map electronic mobilities in-situ & operando OECT channel. The intern will manufacture these OECTs devices in a microelectronics clean room, and will benefit from technical support for their production. He/she will record and analyze the key FoMs through developed nonlinear optics experimentation and electrical and electrochemical characterizations in order to establish, in a more global manner, engineering rules in these PMIECs which will serve as an essential knowledge base in the future, to implement and apply neuromorphic circuits based on OECTs, as the first brick of organic electronics artificial intelligence.

The candidate must have a solid culture in Physics/Materials Science/(Opto)Electronics through their initial training and/or professional experience. This M2 Research internship subject is intended to be continued in a doctoral cycle. Only a student interested in continuing on to a doctorate will therefore be selected for this internship. 🔍 What we are looking for The main evaluation criteria of the candidate will be as follows (list not exhaustive): Technical and scientific mastery in Optics. Experience during previous internships in nonlinear optics and/or microscopy, image analysis by scientific camera will be considered advantageous, Mastery of electronic instrumentation (sCMOS camera, oscilloscope, signal and delay generator, SMU, etc.) and image analysis using a computer (Python, etc.), Aptitude for interdisciplinary work and multidisciplinary collaborations. Autonomy, initiative, Interest in teamwork and ability to build a research project in this context, Proficiency in reading and writing English; Quality of oral and written communication. 📩 Apply Now! · Application deadline: 12/15/2026 · Duration of internship: 6 months · Start of internship: between January 1 and March 1, 2027 · · Internship location: Gardanne (13) - France · Bonuses: at the hourly rate: €4.50 per hour of effective presence Application conditions: Applications must be submitted on the RECRUITEE platform, no later than December 15, 2026(CV, cover letter): The position is open to all with, upon request, accommodations for candidates with disabilities. As part of its Equality, Diversity and Inclusion policy, the École des Mines de Saint Etienne is an employer concerned about fair treatment between candidates. Candidates selected for an audition will be informed as soon as possible. Part of the discussions will take place in English.
