Our scientific research is focused on the understanding of nanoscale materials (2D materials, quantum dots, thin films, molecules) to get insight into novel properties emerging from reduced dimension, interfaces and surfaces. We study their electrical, optical, ferroelectric and magneto-transport properties. These phenomena are investigated using a broad palette of electrical (impedance spectroscopy, transconductance, …), optical (photoconduction, time resolve photocurrent, reflection/transmission) and magnetic (magnetoresistance, SQUID) techniques, in a large range of temperature (400K-1K).
Our multidisciplinary approach is at the frontier between physics, chemistry and materials science. It relies on fabricating and characterizing nanodevices, within the nanofabrication facility of IPCMS STnano, and the 2DLab. It allows us to process and interconnect nanomaterials with nanoscale precision.
Our philosophy is to tackle technologically relevant issues with a rather fundamental approach. This is why patents applications and valorisation projects are actively pursued in the group. Field of applications gather nanoelectronics, spintronics, optoelectronics and neuromorphic computing.
