{{fa>pencil?32}} 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 capacitor
{{fa>pencil?32}} temperature| current range considered| (semiconductor) material| LED color| breakdown voltage of the Z-diode
{{fa>pencil?32}} 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 capacitor
{{fa>pencil?32}} … 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.
{{fa>pencil?32}} 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 bands
{{fa>pencil?32}} … Is dependent on the temperature| … depends on the forward voltage| … is logarithmic concerning the forward voltage| … depends on the reverse voltage
