Teaching activities
I am teaching a wide range of topics ranging from classical mechanics to superconductivity passing through Nanofabrication in clean room facilities and quantum Hall effect measurements at low temperature.

Quantum Hall effect in graphene - Master 2
This lab class consists in fabricating in a clean room environment Hall bars in CVD graphene. The graphene is then used as a two-dimensional electron gas that we cool down to 4.2K in liquid Helium. We then characterize its electrical properties with respect to magnetic field highlighting successively quantum effects that are Shubnikov-de Haas oscillations and the famous quantum Hall effect at high field (5 Teslas). This labclass combines very technical aspects with nanofabrication and low-temperature measurements together with an important theoretical input to understand magnetotransport in graphene (Landau quantization, Landauer-Buttiker formalism).
This labclass is benefitting from the support of Labex LaSips, NanoSaclay and Palm.

Carbon nanotube transistors - Master 2
In this lab class we fabricate in a clean room environment carbon-nanotubes based transistors with optical lithography, e-gun evaporation and lift-off techniques. We then characterize the fabricated devices with scanning electron microscope imaging and room-temperature electrical measurements.

Superconductivity - Master 1
This practical is divided in two experiments. In a first set of experiment the students have to measure the superconducting transition of YBaCuO while measuring the resistance versus temperature. This is done with a computer-controlled acquisition card and a cold stage that cools down to 40K. The second experiment consists in using a SQUID (Superconducting QUantum Interference Device) to measure the Earth's magnetic field and fields generated by common magnets. The SQUID experiment allows to introduce fundamental concepts that are the Josephson effect and the flux quantization.

Waves - L2 Polytech
In these exercice and lab classes, we treat fundamental concepts related to scalar waves. We start introducing definitions of propagating longitudinal waves and transversal waves to finally end with stationnary waves, eigen modes concepts and interferences. Throughout the lecture, we make use of microscopic models to derive d'Alembert's wave equation for sound and wave on a string. We then use this equation to find and use dispersion relations of different propagating media.

Mechanics I - L1S1
We introduce fundamental concepts of classical mechanics such as forces, Newton's laws, kinetic energy theorem, work, potential energy. Fundamental mathematics tools are used for the first time such as differential equations of the first and second kinds. This allows us to treat friction and oscillating behaviours. The exercise class system has evolved since few years with the introduction of "tutorials" as a new pedagogical tool.

Mechanics II - L1S2
Starting from the basic knowledge of mechanics I we further introduce polar, cylindrical, spherical and intrinsic coordinates. We treat non-galilean referentials with the concept of inertial forces. Other fundamental tools such as kinetic momentum, force momentum and the kinetic momentum theorem are introduced. Finally the moment of inertia is treated to deal with extended objects.

Methodology - L1S2
In this lecture we introduce methods to solve simple physics problems for which one a priori has no clue about the answer. This lecture talks about Fermi questions, orders of magnitudes, error propagation... We also use this lecture to realize a mechanical pendulum with smartphones thanks to the application Phyphox. The experimental data are then treated numerically and compared to the theory. At the end of the lecture, the students present one of the major topics of the class in front of their colleagues as an exercise to communicate in front of a crowd.

Free Physics projects - L3S2
The principle of these projects is to let the students conceive and build their own experiment using sensors and tools available in the student lab. The data acquisition is done using Arduino cards, a free and inexpensive technology. At the end the students can share their TP on the open TP platform. These projects promote autonomy and is close from the work of researchers in laboratories.
