We are looking for a highly motivated candidate for the study of radiation and heat transfers on micro / nanometric scales using thermoresistive and infrared probes.
1) Experiments using a thermoresistive probe based on a modified SThM (scanning thermal microscope) operating under vacuum or ambient air in order to study thermal conduction at micro / nano scales:
- Demonstration of the near-field radiative contribution in heat transfers, as well as other conduction channels in various geometries
- Optimization of the experimental setup and data acquisition protocols
- Micro / nano manipulation of individual objects
2) Measurements of infrared thermal radiation at sub-wavelength scales using single-channel and matricial infrared detectors (camera) and development of new optical methods for the study of this radiation beyond the limit of diffraction.
3) Interpretation and modeling of results.
This work is part of an ANR project which involves three academic groups and an industrial group, which is the world leader in the field of glass-based thermal insulation materials. Collaborative exchanges with these partners will be part of this postdoctoral fellowship.
- The candidate must have a doctorate in physics or equivalent.
- He (she) must above all be a very skilful and patient experimenter and have a pronounced taste for instrumentation.
- He (she) should preferably have experience in scanning probe microscopy, micro / nano manipulation, optics, and thermics
- He (she) must be able to program and interface laboratory instruments. Skills in numerical simulation software (Lumerical, Comsol, ...) will be an advantage.
- A reflection is underway at the Langevin Institute on issues related to energy and sustainable development. An interest in these issues will also be a plus.
This work is part of an ANR project which involves three academic groups and an industrial group, which is the world leader in the field of glass-based thermal insulation materials. It aims to improve the understanding of heat exchanges on microscopic scales in order to be able to increase the performance of insulation materials of the future.
A doctoral thesis, which ends this year, has made it possible to develop most of the experimental setups involved in this postdoctoral project. The post-doctoral candidate will be in charge of further improving these asetups while using them at the same time for carrying out experimental studies.
Currently, the position is open for a period of 7 months. A request for additional funding to bring the total duration of the postdoctoral fellowship to at least 12 months is currently in progress. The outcome of this request will be known very soon. Beyond thermics at small scales, an evolution of this position towards the problems linked to energy and sustainable development is envisaged, as well as multiple probe experiments.
Constraints and risks
The candidate will use lasers. He/She will receive a training on laser safety.
