Study Notes
Diode Fundamentals
- The primary function of a diode is to allow current to flow in one direction while blocking it in the other.
Materials Used in Diodes
- Silicon is the most commonly used material for semiconductor diodes today.
History of Diodes
- Ferdinand Braun made the discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal.
Current-Voltage Relationship
- The characteristic of the current-voltage relationship in a semiconductor diode is nonlinear, with the current increasing rapidly as the voltage increases.
Comparison of Diodes
- The primary difference between a semiconductor diode and an obsolete thermionic diode is the method of current flow, with semiconductor diodes using semiconductor materials and thermionic diodes using a heated filament to generate current.
