Igor Stolichnov received his Master degree in solid state physics at Saint Petersburg State Polytechnical University in 1994. In 1996 he joined EPFL, where he was awarded PhD in 2000 for his work on ferroelectric non-volatile memories. Currently he is a senior scientist, member of staff of Nanoelectronic devices laboratory, EPFL. His scientific interests are focused on functional materials and their applications for information processing in energy-efficient circuitry, including ferroelectrics, dielectrics, multiferroics and phase-changing materials. He is active in development of advanced techniques of materials characterization at the nanometer scale, in particular in scanning probe microscopy. His researches that resulted in > 100 publications are focused on functional dielectrics/ferroics, and their integration on semiconductors and metals for applications in information processing and storage.

Cours

Dispositifs micro- nanoélectroniques

EE-333

Surface analysis

MSE-351

The course treats the main surface analysis methods for the characterization of surfaces, interfaces and thin films. It discusses how these methods can be applied to gain specific knowledge about structural, chemical and functional properties of surfaces and thin films. Limitation to 18 students!

Crystalline materials: structures and properties

MSE-306

The properties of crystals and polycrystalline (ceramic) materials including electrical, thermal and electromechanical phenomena are studied in connection with structures, point defects and phase relations. The students learn how to analyse/predict properties based on structure, symmetry and defects
