Objectives
KNOWLEDGE AND UNDERSTANDING

THE COURSE AIMS AT GIVE STUDENTS CONCEPTS AND BASIC NOTIONS TO DESCRIBE SOLID STATE SYSTEMS AND THEIR PROPERTIES. IT ALSO AIMS AT INTRODUCING CONCEPTS AND NOTIONS NEEDED TO UNDERSTAND DEVELOPMENTS AND TRENDS IN THE ANALYSIS OF MATERIALS AND RELATED EXPERIMENTAL TECHNIQUES. AT THE END OF THE COURSE THE STUDENT WILL HAVE GAINED BASIC KNOWLEDGE OF CRYSTALLOGRAPHY, PHENOMENOLOGICAL METHODS TO DERIVE TRANSPORT PROPERTIES AND HE WILL HAVE GAINED KNOWLEDGE IN THE MOST USED EXPERIMENTAL TECHNIQUES TO STUDY SOLIDS. MOREOVER, THE STUDENT WILL KNOW THE TERMINOLOGY AND THEORY WITHIN THIS FIELD OF PHYSICS TOGETHER WITH THE WORKING PRINCIPLES OF COMMON DEVICES.

APPLICATION OF KNOWLEDGE AND UNDERSTANDING

AT THE END OF THE COURSE THE STUDENT WILL BE ABLE TO APPLY THE ACQUIRED KNOWLEDGE TO SOLVE SIMPLE PROBLEMS OF SOLID STATE PHYSICS. THE STUDENT WILL BE ABLE TO APPLY THE KNOWLEDGE OF PHENOMENOLOGICAL MODELS OF SOLID STATE PHYSICS IN ORDER TO UNDERSTAND ELECTRONIC/OPTICAL/STRUCTURAL/MAGNETIC AND THERMAL PROPERTIES OF MATERIALS AND WILL BE ABLE TO EVALUATE ORDER OF MAGNITUDES, PERFORM ELEMENTARY CALCULATIONS AND SOLVE SIMPLE PROBLEMS CONCERNING MATERIAL PROPERTIES
Prerequisites
TEACHING ASSUMES KNOWLEDGE OF CLASSICAL MECHANICS, ANALYTICAL MECHANICS, AND ELECTROMAGNETISM. THE TEACHING ASSUMES THAT THE STUDENT KNOWS HOW TO PERFORM DIAGONALIZATION OF MATRICES AND COMPUTATION OF EIGENVALUES AND EIGENVECTORS AND SOLVE ONE-DIMENSIONAL QUANTUM PROBLEMS.
Contents
QUANTUM MECHANICS: PARTICLE IN AN INFINITE POTENTIAL WELL IN ONE AND MORE DIMENSIONS; ENERGY LEVELS; PERIODIC POTENTIALS; BLOCH THEOREM. GENERAL PROPERTIES OF FREE ELECTRON GAS. SOMMERFELD MODEL. DENSITY OF STATES. DENSITIES OF STATES FOR MESOSCOPIC STRUCTURES. (6 HOURS)
INTRODUCTION TO CRYSTAL FIELD THEORY. EIGENFUNCTIONS OF THE CRYSTAL FIELD POTENTIAL. CRYSTAL FIELD AND P AND D ORBITALS. GENERAL CRYSTAL FIELD THEORY. (10 HOURS)
STATEMENT OF THE JAHN-TELLER THEOREM. OCCUPATION OF ENERGY LEVELS IN TWO-DIMENSIONAL SQUARE AND RECTANGULAR POTENTIALS. GROUND STATE AS VAROIUS FILLINGS. MODES OF DEFORMATION OF A TRIANGULAR MOLECULE. (6 HOURS)
METALLIC BONDS. DIRECTING COSINES. HOPPING MATRICES. SLATER-KOSTER INTEGRALS FOR ATOMIC MOLECULES. REAL P, D AND F ORBITALS. SLATER-KOSTER INTEGRALS FOR F ORBITALS. (5 HOURS)
SPIN-ORBIT INTERACTION. DERIVATION AND SIMPLIFIED TREATMENT. EFFECT OF SPIN-ORBIT INTERACTION ON P ORBITALS. REMOVAL OF DEGENERACY IN SPIN AND NEW ENERGY LEVELS. CASE OF D ORBITALS. (5 HOURS)
FABRICATION OF MATERIALS IN THE FORM OF THIN FILMS (FOCUS ON SPUTTERING AND ELECTRON-BEAM TECHNIQUES) (5 HOURS);
STRUCTURAL CHARACTERIZATIONS: X-RAY DIFFRACTOMETRY AND/OR RAMAN SPECTROSCOPY - THEORY AND SPECTRUM MEASUREMENTS (6 HOURS);
ELECTRICAL CHARACTERIZATION: TRANSPORT MEASUREMENTS (8 HOURS);
DENSITY OF STATES MEASUREMENTS (5 HOURS).
Teaching Methods
THE COURSE INCLUDES 48 HOURS OF TEACHING (6 CFU), CONSISTING OF LECTURES (4 CFU) AND LABORATORY ACTIVITIES (2 CFU). IN PARTICULAR, THERE ARE 32 HOURS OF LECTURES AND 16 HOURS OF LABORATORY.
IN THE LECTURES ARE PRESENTED THE TOPICS OF THE COURSE FOLLOWING THE HISTORICAL DEVELOPMENT OF THE DISCIPLINE. IN THE LABORATORY ACTIVITIES WILL BE REALIZED SIMPLE EXPERIMENTS RELATED TO WHAT PREVIOUSLY TREATED FROM A THEORETICAL POINT OF VIEW. THE ATTENDANCE OF THE COURSE, ALTHOUGH NOT MANDATORY, IS STRONGLY RECOMMENDED, ESPECIALLY FOR WHAT CONCERNS THE LABORATORY ACTIVITIES. THE STUDENT HAS THE OPPORTUNITY TO USE THE E-LEARNING PLATFORM TO DOWNLOAD DIDACTIC MATERIALS (PROBLEMS AND REFERENCE TEXTS) AND TO GET INFORMATION ABOUT THE TOPICS COVERED IN CLASS.
Verification of learning
THE PURPOSE OF THE EXAMINATION IS TO EVALUATE THE KNOWLEDGE OF THE FUNDAMENTAL PRINCIPLES OF SOLID STATE PHYSICS.
THE EXAM INCLUDES AN ORAL TEST, EVALUATED IN THIRTIETHS. THE EVALUATION OF THE ORAL TEST WILL TAKE INTO ACCOUNT THE ABILITY TO IDENTIFY THE MOST APPROPRIATE STRATEGIES TO ANALYZE THE TOPICS OF THE COURSE, THE ABILITY TO EXPOSE IN A CLEAR AND SYNTHETIC WAY THE OBJECTIVES, THE PROCEDURE AND THE RESULTS OF THE WORK CARRIED OUT, AS WELL AS THE ABILITY TO DEEPEN THE TOPICS COVERED, ORIENTING HIMSELF APPROPRIATELY AMONG THE PROPOSED MATERIALS.
THE MINIMUM LEVEL OF EVALUATION (18/30) IS GIVEN WHEN THE STUDENT DEMONSTRATES THE KNOWLEDGE OF THE FUNDAMENTAL CONCEPTS OF SOLID STATE PHYSICS, SHOWING ALSO A KNOWLEDGE OF THE MAIN EXPERIMENTAL TECHNIQUES AND METHODOLOGIES AND A REASONABLE EXPOSITIVE ABILITY.
THE HIGHEST LEVEL (30/30) IS AWARDED WHEN THE STUDENT DEMONSTRATES THE ABILITY TO CORRECTLY ILLUSTRATE AND COMPETENTLY DISCUSS THE CONCEPTS, METHODS AND EXPERIMENTAL TECHNIQUES PROPER TO SOLID STATE PHYSICS AND SHOWS A REMARKABLE ABILITY TO LINK AND PRESENT THE PROPERTIES OF THE DIFFERENT TOPICS.
HONORS ARE AWARDED WHEN THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THE THEORETICAL AND OPERATIONAL CONTENTS AND SHOWS THE ABILITY TO PRESENT THE TOPICS WITH REMARKABLE LANGUAGE AND AUTONOMOUS ELABORATION SKILLS EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED BY THE TEACHER.
