Sujet du postdoc :

Scanning Thermal Microscopy is becoming a powerful technique to study the thermal properties of materials and devices at micro and nanoscales. It can provide information about heat generation and propagation in operating devices, showing the
presence of hot spots and defects. It can also provide quantitative data about the local thermal conductivity of nanostructured materials. Several European research teams recently joined their efforts to better understand the potentialities of Scanning Thermal Microscopes and for solving problems in nanothermics (Quantiheat European project).

Thématique de recherche :

The researcher will carry on several experimental studies on devices fabricated during the Quantiheat project. He/she will perform scanning thermal measurements with the fluorescent-SThM recently developed at ESPCI. The researcher will :
i) characterize the thermo-optical properties of fluorescent particles,
ii) measure thermal maps on various devices such as microwires and nanowires,
iii) study heat transfers between the tip and the surface,
iv) interact with other teams that are involved in the project.

Compétences requises :

Experimental work, experience in scanning probe microscopy / fluorescence microscopy needed

Début :

January/February 2015,

Durée :
