Goal of the courseThis course is the last compulsory lab session of the undergraduate curriculum. It consists of a set of experiments on modern physics. The students attending have to be prepared and to have studied the basic theory and notions of the experiments they conduct. After each lab session they have to prepare and handle a full lab report. Attendance is obligatory and during each session the students’ preparation is examined by the professor.
SyllabusThe experiments are conducted in groups of two students. The scheduled experiments are:
Vacuum Methods: Principles of vacuum systems, Mechanical pumps, Diffusion pumps, Rirani gauge, Penning gauge, Pumping speed, Conduction, Leaks Ferromagnetic Hysteresis: Magnetic dipole moment, Paramagnetism, Diamagnetism, Ferromagnetism, Curie temperature, Ampere law, Magnetic permeability
Hall Effect: Lorentz force, Hall voltage, Hall coefficient in metals and semiconductors, Carrier types, Carrier mobility, Hall effect measurement of carrier density and mobility in semiconductors, Magnetoresistance, Quantum Hall effect.
Franck-Hertz Experiment: Bohr’s atomic model, Electrons scattering by atoms, Ionization potential, Hg vapor tube.
Photoelectric Effect: The photoelectric effect and the dual (wave-particle) nature of light, Planck’s constant, Atomic emission spectra, Experimental apparatus: photodiode, diffraction grating, spectroscope.
Zeeman Effect: Electron spin, Spin-orbit coupling, Lande g-factor, Total angular momentum and total atomic magnetic moment, Normal Zeeman effect, Anomalous Zeeman effect and Paschen-Bach effect.
