Mesoscopic physics

Our research group studies mesoscopic physics and electronic transport properties of semiconductor microstructures for the design of new generations of electronic nano-devices and information technologies.

The group studies the physical, electronic and mesoscopic transport properties in nanostructures made on multilayers and low dimensional semiconductors : ballistic transport, dynamical chaos, weak localization, metal-insulator transition, coherent diffusion of electrons, phase coherence, Coulomb blockade, spin phenomena, Kondo and Aharonov-Bohm effects in quantum interferometer of diameter < 80 nm , disordered two-dimensional topological insulators...

Transport in nanowires, nanoparticles, point contacts, antidot arrays under microwave irradiation microwave induced photovoltage and photoresistance

The developed investigation tools are very specific for superconducting magnets up to 17T and high magnetic fields, (continuous up to 35 T produced with resistive magnets). They are associated to multiple and extreme conditions of temperature range (30 mK – 300 K), high hydrostatic pressure (28 Kbars), visible and infrared magneto-photo-optics, NMR (100 MHz) and microwave irradiation (linearly polarized) from GHz to 0.4 THz.
