Prerequisites
Basic Knowledge of Solid State, quantum mechanics and basic concepts of Materials Science.
Objectives and Contextualisation
Deepen the understanding of size effects in the properties of low-dimensional materials.
Competences
- Analyse the benefits of nanotechnology products, within one's specialisation, and understand their origins at a basic level
- Continue the learning process, to a large extent autonomously
- Design processes for nanomaterials with properties and functionalities default (specialty Nanomaterials).
- 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.
Learning Outcomes
- Assess the importance of scale for describing advanced physical properties in materials, whether electronic, optical, magnetic, mechanical or transport-related.
- Continue the learning process, to a large extent autonomously
- Describe in qualitative terms the principles behind superconductivity and know its applications.
- Identify the emergence of thermoelectric phenomena at the nanometric scale.
- Interpret the phenomena of light absorption and emission, both interband and intraband, in nanostructures.

Content
Electronic and Optical properties: Energy bands. K.p and pseudopotencials. Optical properties of low-dimensional semiconductors. Light absorption. Spontaneous and stimulated emission. Luminiscence. Pressure effects.
Transport: electrons and phonons. kinetic theory. Boltzmann transport equation. Landauer formalism: Conductance and fluxes. Aplication to low-dimensional semiconductors and graphene. Thermoelectric effects in semiconductor nanostructures.
Mechanical properties: Correlation of the microstructure with mechanical properties: Hall-Petch effect. Nanoindentation: Oliver & Pharr Method. Size effects. Nanoindentation in crystalline and amorphous solids.
Superconductivity: This part is focused on the study of superconducting materials. We will describe the basic properties of a superconductor; including the phenomenon of zero resistance, the Meissner and Josephson effects, type I and type II superconductors, and the different theoretical approaches developed to understand the superconducting state. The importance of nanotechnology, and its implication on the powerful applications of superconducting materials will be revised.
Methodology
Students have notes in the Virtual Campus or pdf copies before class.
Lessons: The teacher explains the most important concepts of each subject. The notes will be available at the Virtual campus or distributed by the professor.
Discussion lectures: reading of scientific articles and their discussion in class.
Supervised activities: In specified hours the teachers will be accessible to discuss the contents of their respective subjects.
Self-learning activities: Solving problems and studying.
Handouts: teachers can ask for research, bibliographic works or problem solving to consolidate the contents of every subject.
Study for exams: Personal work by the student.
