Prerequisites
Basic physics (mechanics, electrostatic, optics....). Fundamentals of electronic devices.
Objectives and Contextualisation
The module aims to give students an overview of nanoelectromechanical systems, their main properties and applications. The physical principles that governs the behavior of the NEMS and the boundaries between classical and quantum models will be also established.
Competences
- Analyse the benefits of nanotechnology products, within one's specialisation, and understand their origins at a basic level
- Communicate and justify conclusions clearly and unambiguously to both specialised and non-specialised audiences.
- Continue the learning process, to a large extent autonomously
- Critically analyze the principles of operation and expected benefits of electronic devices operating at the nanoscale (nano-electronics specialty)
- Design, plan and carry out a research project in nanoscience and nanotechnology.
- Identify and distinguish the synthesis/manufacture techniques for nanomaterials and nanodevices typically adopted in one's specialisation.
- Identify the characterisation and analysis techniques typically adopted in nanotechnology and know the principles behind these, within one's specialisation.
- Show expertise in using scientific terminology and explaining research results in the context of scientific production, in order to understand and interact effectively with other professionals.
- Solve problems in new or little-known situations within broader (or multidisciplinary) contexts related to the field of study.
- Use acquired knowledge as a basis for originality in the application of ideas, often in a research context.

Content
- NEMS fundamentals. Nanomechanics.
- Non-linear dynamics. Modal coupling and collaborative behaviour. Noise
- NEMS fabrication and system integration (NEMS engineering)
- NEMS transduction techniques: electrical-optical-thermal-mechanical based techniques. Self-actuation.
- Carbon-based NEMS
- Applications and perspectives of NEMS. NEMS for probing mesoscopic effects & quantum properties. NEMS as emerging new devices (switches, oscillators, energy harvesting, sensors)
Methodology
Theory: Oral exposition of the fundamentals concepts. Concepts will be partially introduced by experts during the seminars.
Laboratory: Hands-on specific tools for NEMS design and analysis. Finite elements simulations. Characterization of non-linear properties of resonators.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The evaluation of the subject will have 3 differentiated sections:
a) Synthesis written test of the subject (35%), and with a rating above 4 to average with the remaining qualifications. This synthesis test can be retrieved with the final recovery exam (at the end of the semester), requiring a 4 to average.
b) Oral presentation of one of the cases worked. Obligatory and non-recoverable activity (35%).
c) Laboratory with two marks: Attendance and active participation in the laboratory sessions. Obligatory and non-recoverable activity (5%) and Written report of the work carried out in the laboratory, paying special attention to the interpretation and discussion of the results compared to those awaited theoretically and/or simulated (25%). This work is mandatory and non-recoverable.
The "Not evaluable" qualification will only be awarded if the student does not participate in any evaluation activities (attendance to the laboratory sessions, oral presentation, exams)
