Functional nano-circuits at artificial laminar MULTIferroic interfaces by NANOlithography

Novel technologies need to be compatible with sustainable growth and require devices to use less materials and to consume less energy. Miniaturization has been the major route for decades, with great success in the field of microelectronics. Correlatively, using multifunctional compounds, providing several usable degrees of freedom or functions is another potential strategy. Ideally both approaches should converge in multifunctional nanoscale devices: the MULTINANO project goal. Within this project we will realize functioning devices including multifunctional components sensitive to a variety of external stimuli. The interconnection will be intrinsically embedded and can be reduced to nanoscale scales.

Nanolithography will be performed on single crystalline laminar heterostructures grown by molecular beam epitaxy. Laser lithography will allow realizing variable in plane compositions. The nano-circuits and devices will be investigated for structure, chemistry and magnetic properties, under operation (and until failure) at the micron- and nano- scale using state-of-the-art rastering or full-field techniques available at synchrotron radiation sources. First-principles calculations will be used to unravel the mechanisms leading to the interface charge trapping as well as to determine the optimal device configurations.
