CODE 72246 ACADEMIC YEAR 2022/2023 CREDITS 5 cfu anno 3 SCIENZA DEI MATERIALI 8765 (L-30) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR FIS/03 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester MODULES Questo insegnamento è un modulo di: PHYSICS OF MATERIALS WITH LABORATORY TEACHING MATERIALS AULAWEB OVERVIEW the second module focuses on the analysis of the electrical and thermoelectric transport properties in various materials, analyzing their characteristics starting from the band structure AIMS AND CONTENT LEARNING OUTCOMES The course aims to: describe a wide range of techniques and experimental data relating to thermal, thermoelectric and electrical properties, to provide the basic interpretative models for their understanding and to define the characteristic parameters of the materials. AIMS AND LEARNING OUTCOMES The specific educational objective of this module is to make the student acquire the skills necessary to be able to analyze experimental measures of transport properties and to be able to derive from them fundamental characteristics of the material measured. At the end of the module the student will also have acquired the basics of various methods of preparation and characterization of materials such as lamination, thin film deposition, X-ray diffractometry or resistivity and Hall effect measurements. TEACHING METHODS lectures on the blackboard with the aid of powerpoint presentations to illustrate measurement techniques and experimental data SYLLABUS/CONTENT - free electron model and Drude model. Application to experimental measurements of electrical properties in metals. - Sommerfeld model - derivation of the band structure in a solid. Example of a semiconductor material - characteristics of a semiconductor material. Electrons and holes, two-band Drude model - dependence of resistivity on temperature. Bloch Gruneisen Laboratory activities 4-wire resistance measurement and determination of the most important experimental errors in a resistivity measurement Lamination of copper specimens with different defect density and measurement of resistivity as a function of temperature Measurement of carrier density in a conductive material by means of Hall effect experiments RECOMMENDED READING/BIBLIOGRAPHY Kittel - Introduction to solid state physics Aschroft and Mermin - Solid state physics TEACHERS AND EXAM BOARD DANIELE MARRE' ALESSANDRO LEVERATTO EMILIO BELLINGERI Exam Board DANIELE MARRE' (President) EMILIO BELLINGERI ALESSANDRO LEVERATTO MARINA PUTTI LUCA VATTUONE (President Substitute) LESSONS Class schedule PHYSICS OF MATERIALS WITH LABORATORY (MODULE 2) EXAMS Exam schedule Data appello Orario Luogo Degree type Note 10/01/2023 09:15 GENOVA Orale 13/02/2023 09:00 GENOVA Orale 13/06/2023 09:00 GENOVA Orale 10/07/2023 09:00 GENOVA Orale 11/09/2023 09:00 GENOVA Orale 09/10/2023 09:00 GENOVA Orale
