DETAIL
Due to the characteristics of diodes, they are often used as rectifiers in electric power engineering (converting alternating current into direct current); in electronic engineering they are often used as detectors (to detect echo waves from amplitude modulated waves); and in computer hardware logic design they are often used as logic Circuit logic gate.
In 1874, German physicist Karl Braun discovered the rectifying ability of crystals at the Karlsruhe Institute of Technology. Therefore, the first-generation diode developed in 1906, the "whisker diode", was made of mineral crystals such as galena. Early diodes also included vacuum tubes. Vacuum tube diodes had two electrodes, an anode and a hot cathode. The voltage applied between the electrodes allowed hot electrons to travel from the cathode to the anode, thus having a rectifying effect. .
After the properties of semiconductors were discovered, semiconductor diodes became the world's first semiconductor components. Today's diodes are mostly produced using silicon, and other semiconductor materials such as germanium are sometimes used. The most common structure at present is that a crystalline chip with semiconductor properties is connected to two electrical terminals through a PN junction.
