PHYSICAL CHARACTERIZATION OF MATERIALS WITH LABORATORY
Fundamentals of the structure of matter.
Oral examination concerning the arguments of the lessons and a discussion on the experimental activity performed.
The course includes two parts with one final examination. The first part consists in lessons aimed at the presentation of the fundamental concepts of optical and vibrational spectroscopy of solids, together with the description of selected experimental techniques; the second part consists in an experimental activity.
Optical and vibrational spectroscopy of solids. Introduction to selected experimental techniques
Lessons (4 CFU)
Maxwell equations. Interactions between electromagnetic radiation and matter: analyses of charges and currents in a solid; polarizability, susceptibility; the complex dielectric function, complex refractive index, dielectric tensor; Lorentz and Drude models; light dispersion, absorption, reflectivity; the local field; linear response functions and Kramers-Kronig relations; fundamentals of non linear optics; neutron spectroscopy; photoemission.
Experimental techniques of optical and vibrational spectroscopy: anelastic (Brillouin, Raman) scattering; optical absorption; photoluminescence and time resolved luminescence; radio-luminescence and scintillation.
Electron paramagnetic resonance. Principles of scanning probe microscopy techniques.
Experimental activity (4 CFU)
Execution of one experimental activity among the following topics:
spectroscopy of semiconductors
analysis of trace elements by ICP-Mass
thermoluminescence applied to archeological dating or to defect analysis
atomic force microscopy
electron spin resonance
optical spectroscopy of insulators
A written final report describing the experimental activity is required.
