Aim of the course is to provide the fundamental knowledges on the technologies and design for nanostructures and nanosystems , with particular emphasis on applications in the ICT area. This course plays a central role in the development of an Engineer expert in nanotechnologies, because it extensively provides the basic elements for understanding how to study, understand and design a system based on emerging devices at the nanoscale both based on conventional and new principles, and how to connect them in more conventional microelectronics systems.

Expected knowledge: • development of knowledge that extends and/or reinforces the ones received from preparatory courses and allow to develop and/or apply original ideas and design methods and the development of nanocircuits and nanosystems; • ability to apply the knowledge gained in a research and/or industrial framework, understanding capability and skills in solving problems related to the design, modeling, simulation and implementation of nanosystems also applied to new technological principles or unfamiliar issues or entered into application contexts broader and more interdisciplinary than the engineering sector (medicine, environmental monitoring, food, ...); • ability to integrate technical knowledge and to manage the complexity of the design a, to evaluate the quality and robustness of a nanosystem, its implementation and feasibility, choosing the most efficient solutions from the available options; • ability to communicate in a clear and unambiguous way technical aspects relating to the design and manufacture of integrated circuits at the nanoscale, both in writing and oral form and to both specialists and non-specialists; • development of self-learning skills to allow the student to continue to learn autonomously new techniques and design methodologies for integrated nano systems, not necessarily explained and described during the course.

• Elementary physics (elements of structure of matter) • Elements of modern physics • Elements of electronics • Elements of electronic devices . Knowledges on magnetism

- Methods for modeling nanodevices and nanocircuits for the hierarchical design of micro and nano systems. - Simulation, methods for integration and test of nano systems. - Molecular devices: molecular wires, molecular diodes, molecular transistors, molecular sensors. - Silicon based nanowires and nanosensors. - Field Coupled Nanodevices for computation based on molecules, on nanomagnets and single atoms. - Magnetic devices and systems for memory and computation.

The course consists both in lectures delivered by slides and using blackboards, and of laboratories aimed at simulating, evaluating and designing single devices and nano systems. The slides and laboratory material will be made available to students on the internet Didactic Portal, and the CAD system and models for the laboratory exercise will be available and usable during the whole semester. The structure of the course involves the study of: - Theory on conduction in 3D, 2D, 1D, 0D systems. - Device structure and impact of technological parameters on the physical behaviour and on conduction for molecular wires, diodes, transistors, sensors, and for silicon based 1D systems. - Modelling of molecular wires, diodes, transistors, sensors and silicon nanowires . - Design of circuits and nanosystems based on molecular devices based on conduction and silicon nanowires. - Theory on field-coupling information transmission at molecular level. - Device structure and impact of technological parameters on the physical behaviour and on field coupling information transmission for field-coupling molecular devices. - Theory on field-coupling information propagation in magnetic devices. - Device structure and impact of technological parameters on the physical behaviour and on filed coupling information for modeling of field-coupling based molecular and magnetic devices. - Desing of circuits and nanosystems based on field-coupling principles. - Magnetic memories organization and design and interfaces to microelectronics circuits. - Resistive memories organization and design and interfaces to microelectronics circuits. Four laboratories on the main topics will also be organized using cad tools for the analysis, modeling and design of nanodevices and nanocircuits.

The material (slides, scientific papers, material for the lab execution) will be available, and some books will be suggested as integration by the teacher.
