Prof. Colombo Bolognesi

Lecture Contents 


Understanding of the basic principles of semiconductor devices in micro-, opto-, and power electronics.


  • Brief survey of the history of microelectronics.
  • Basic physics: crystal structure of solids, properties of silicon and other semiconductors, principles of quantum mechanics, band model, conductivity, dispersion relation, equilibrium statistics, transport equations, generation-recombination (G-R).
  • Quasi-Fermi levels: physical and electrical properties of the pn-junction. 
  • Pn-diode: characteristics, small-signal behaviour, G-R currents, ideality factor, junction breakdown.
  • Contacts: rectifying barrier. 
  • Bipolar transistor: operation principles, modes of operation, characteristics, models, simulation.
  • MOS devices: band diagram, MOSFET operation, CV- and IV characteristics, frequency limitations and non-ideal behaviour.
