Contents Wave properties of electromagnetic radiation.
Introduction to quantum mechanics.
Schrödinger's theory of Quantum Mechanics.
Bonds, molecules and crystals.
Free electron gas and band structure of solids.
Elements of Soft Matter Physics
Reference texts Notes provided by the teacher.
Educational objectives Knowledge of the fundamentals of modern physics and elementary quantum mechanics, applied to the study of atoms, molecules, solids and soft matter.
Prerequisites None
Teaching methods The course is articulated in
1) Theoretical lessons
2) Exercises and demonstrative experiments
Learning verification modality Written test that requires the solution of open and / or closed-response questions, to be completed in 2 hours. The purpose of the test is to ascertain: i) the ability to understand the theoretical contents of the course (Dublin descriptor 1), ii) the ability to expose and correctly apply theoretical knowledge (Dublin descriptor 2), iii) Ability to autonomously formulate appropriate judgments and observations on possible alternative model (Dublin descriptor 3), iv) the ability in effective and pertinent written communication (Dublin 4 descriptor).

Educational objectives The course aims, through a combined description of theoretical and experimental methodologies, to provide the student with a detailed knowledge from the chemical and physical point of view of the processes that characterise materials for most of the technological applications, with particular attention to the (micro)electronic and optoelectronic field.
Prerequisites Basic knowledge of Inorganic Chemistry, Physics, and mathematics. Good level (ideally B2) of English language knowledge (understanding, speaking, writing)
Teaching methods Lectures and computational exercises
Learning verification modality The exam consists of a 2 hrs written test (~10 numerical exercises) followed by a 10-15 mins oral test to verify the student knowledge level and understanding of the theoretical and methodological contents of the course.
