My PhD focused on the study and fabrication of very low subthreshold-slope transistors, called I-MOSFETs (Impact Ionization MOSFETs). These devices were based on III-V semiconductors in order to obtain a very low supply voltage. We then developed and optimized nanofabrication of devices using different techniques (ALD, ICP-RIE, lithography tools) and characterized them by different techniques such as SEM, XPS analysis or electrical measurements.

Teacher Assistant
-
Sep 2014 - Sep 2016
During my PhD, I teached (practical only) to bachelor's degree students. The main teaching were : - Basics of electronics in which the student learned to know the main experimental tools in electronics and how to use them in a practical case. - Electrokinetics in which the student learned the basic laws of electrokinetics and how to apply them in a pratical case. - Applied physics in which the student learned the different laws of statistical physics, of the thermal and electrical conductivity in metals and semiconductor and Hall effect in semiconductors.

Feb 2013 - Jul 2013
During this internship, we studied the dynamics of a binary liquid confined in different mesoporous materials. We principaly used NMR characterization in order to observe the behavious under confinement. These experiments were done at The University of Rennes 1 and at the University of Adam-Mickiewicz in Poznan (Poland).

During this internship, we studied the structure of a binary liquid (alcohol and solvant) confined in a mesoporous material (silica). Different techniques were used such as Raman Spectroscopy, XRD or neutron scattering and dielectric spectroscopy. Besides, the silica was functionnalized in order study the structural behaviour of the liquid.

During this internship, we studied the inverse melting transition of a ternary liquid using differential scanning callorimetry technique. Then we observed it's behaviour when confined in a mesoporous material (silica).
