Research :
After a doctorate about the photoelectrochemitry of III-V compound semiconductors, I joined Prof. Heinz Gerischer in Berlin to study silicon anisotropic etching using in situ STM with atomic resolution. Since then I developed a surface science approach of electrochemical interface aiming at synthesizing and characterizing functional nanostructures of interest in different fields. My current and past research includes :
The organic modification of silicon surfaces to elaborate efficient photoswitching surfaces, template to grow multiferroic films and heterostructures, and develop new biosensors.
Magnetic ultrathin films with emphasis on magnetic anisotropy, influence of the electric field, and role of local atomic environment (alloys, surface chemistry)
Fundamental aspects of electrochemical deposition with emphasis on the codeposition, deposition on bimetallic surfaces, and also metal on Si deposition.
Electrochemical nanolithography with an electrochemical AFM,
Silicon anisotropic etching,
