Thermal devices and thermometry
Accurate temperature measurement with high spatial and temporal resolution is a challenging research topic. Advances in nanosciences and nanobiotechnologies require precise thermometry down to the nanoscale regime where conventional methods are no more relevant. The development of a nanoscale thermometer is not only a matter of size, but also requires materials with novel physical properties along with dedicated nanocharacterization techniques. This project aims at developing thermal nanocharacterization techniques with a high spatial and temporal resolution in dry and liquid conditions using fluorescent probes or phase transition materials.
