P-doping produces quasi-free electrons Conductivity in semiconductors happens via conduction band and valence band The diode blocks at any negative voltage (reverse voltage). The diode can be modeled as a voltage source and capacitorcheck answersExercise - Quiz On which physical properties does the forward voltage $U_S$ depend? temperature current range considered (semiconductor) material LED color breakdown voltage of the Z-diodecheck answersExercise - Quiz Which statement(s) about the junction is/are correct? There is no electric field in the junction The junction does not contain free charge carriers The junction becomes larger when current is passed through it Electron-hole pairs are created in the junction by photons The junction is enlarged in the Schottky diode compared to the PN diode The junction forms a capacitorcheck answersExercise - Quiz The forward voltage … … for silicon is fixed about 0.6 … 0.7 V … serves to allow electrons to cross the bandgap … depends on the current range under consideration … is smaller for germanium diodes than for silicon diodes.check answersExercise - Quiz Statements about the conduction/valence band Photon capture can move electrons from the conduction band to the valence band “Recombination” removes an electron from the valence band and a hole from the conduction band A donor creates one or more quasi-free electrons The band gap indicates the maximum energetic distance between the conduction and valence bandscheck answersExercise - Quiz The forward current … … Is dependent on the temperature … depends on the forward voltage … is logarithmic concerning the forward voltage … depends on the reverse voltagecheck answers
