The course aims to provide the key elements for understanding the basic physical interactions that govern the behavior of materials under different mechanical, electrical and optical stresses. At the end of the course the student must know the main interaction mechanisms in materials and must be able to evaluate the characteristics of a material on the basis of the type of response obtained with specific experiments for measuring physical parameters.
Course Prerequisites
Although some useful concepts will be resumed in the first part of the course, a knowledge of the basics of general physics is required; in particular the notions of Force and fields of force, energy and potential, the concepts of electric charge and magnetic dipole and those of Temperature and current.
Teaching Methods
The teaching uses lectures and guided problem solving in the classroom, supplemented by two practical exercises carried out by students in laboratory groups. Presentations made available to students in the section dedicated to teaching on the KIRO platform are used for the conduct of lectures.
Assessment Methods
The learning test will take place in written form and will generally include 2 questions that require a short answer concerning the relationship between structure and properties of the materials, aimed at verifying the acquisition of the concepts and terminology developed in class, and the solution of 1 numerical question.
Texts
For the lessons, chapters or paragraphs from the following texts will be taken as references from time to time: Introduction to Solid State Physics, author: Charles Kittel, 8th Edition, edited by Wiley ISBN: 978-0-471-41526-8 Solid State Physics, authors: Neil Ashcroft and N. Mermin, edited by Cengage Learning, Inc.
Contents
the first part of the course (1 CFU) should be devoted to recover and reinforce some preliminary competences required: basis of forces (mechanical and electro-magnetical), field and potential, electromagnetism, charges and currents, Ohm laws, capacitance, Maxwell equations, dielectric function. Then, starting from the crystallographic structure and bonds in solids, the following topics will be developed. Mechanical properties: cohesion energy, elastic properties, propagation of mechanical waves, expansion and compression, vibrational properties. Electronic properties: electronic bands and statistics, metals, semiconductors and insulators, charge carriers and electronic transport, doping and diffusion. Optical properties: refractive index and extinction coefficient, complex formalism of wave propagation, electromagnetic waves in a material medium, thin film and multilayer optics, interferometry.
