Missions

In various applications, from pollution monitoring to medical treatment, the systematic measurement of ions holds significant importance. Despite the availability of operational devices, developing affordable, portable, and accurate tools for measuring ions in solutions has proven challenging due to limitations in versatility and durability. In this context, promising proof of concepts of alternative devices, not reliant on selective layers have been shown [R. Sivakumarasamy et al. Nat.Mat. 17, 464 (2018)]. In this project, through precise control of nano-transistors interface properties and microfluidics, we aim to bring this approach to a stage where practical applications can be realized. The final objective is to demonstrate the capability of monitoring hyponatremia in blood with a high precision level, that can represent a significant step toward enhancing domiciliary medicine for cirrhosis patients in the future.
The postdoctoral fellow will lead the development, fabrication, and characterization of nanotransistors featuring various oxide surfaces, stress conditions, and geometries to investigate ion-specific interactions. One goal is to establish a direct correlation between the fabrication and design of nanotransistors and their detection capabilities. Another objective is to demonstrate the feasibility of selectively measuring Na+ in blood serum using a nanotransistor without a selective layer.

Activities

- Development and fabrication of nanotransistors incorporating various process and geometries.
- Structural characterization using SEM and FIB, as well as electrical characterization under both dry and wet conditions.
- Integration of sensing devices with microfluidics for proof-of-concept demonstrations.

Skills

- The candidate must be a recent PhD graduate (within the last three years) in nanotechnology, applied physics or bioelectronics.
- Successful demonstrations of nanofabrication in a clean room environment are mandatory. Experience in Si based technology or advanced transistors processing is a plus.
- a strong taste of experimental work and good team-work capacity (interactions to foresee with other members of the project consortium as well as with technical staff)
- Fluency in spoken and written English.
- Ability to prioritize own workload to deal with urgent tasks, while maintaining a high standard of accuracy and attention to detail.

Work Context

With a large number of permanent researchers, engineers and PhD students as well as strong interactions with industry, the LAAS-CNRS is situated at the crossing between scientific research, innovation and applications. The LAAS-CNRS possesses one of the most important technological installations dedicated to research, with an ultra-modern cleanroom of 1600m². The project will benefit furthermore from the novel chemistry and biology (microfluidic, blood experiments). The project will mainly be carried out in the host laboratory in Toulouse, and also the post-doc will work in a very stimulating context of international research. Numerous exchanges and interactions with the project partners (France and Japan) will stimulate the multidisciplinary research.

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
