What are the basics of diode construction?
The
diode design follows several very basic instructions. In its simplest form, electricity moves into the anode over semiconductor and out through the cathode. Due to the design of the diode itself, electricity cannot move back through the structure, which makes the average diode in one way. Although there are many versions of diodes, most of them are a small variation on this basic model.
When the power flows through the diode, it can only go in one direction. This is usually from the anode to the cathode and out, but not always. In any situation where the device receives strength to operate, the device works. If the item generates power, then the flow goes the opposite. This second case is unusual and leads to many people to the belief that standard diodes are always one -way, which is a common misconception in the design of the diode. This is a metal power, often made of zinc, on the outside of the diode. It attracts positively charged anions and attracts tension into it.
Inside the diode, the current returns to semiconductive material. This phase of constructionCE diodes usually use silicon or Germanium, but sometimes other materials are also used. The semiconductor consists of two zones, each of which was subsidized. Doping is a method of adding additional material to the semiconductor to change its properties.
The first area is called PO semiconductor. This area was subsidized by a metal substance such as boor or aluminum. This gives the areas a slightly positive charge and helps pull electricity out of the anode.
The second area of the semiconductor is type N. This part can be subsidized with a wide range of metals, mostly depending on what the basic semiconductor is made of. Two of the more common dopants for type N are phosphorus and arsenic. These metals give semiconductors a slight negative charge.
There is a gap between P and N-Type semiconductors, creating one of the main variations in the diode construction. This zone can contain a small physical gap, secondary systems such as Svět SystemsTLE emitting diode or simply materials that change the way the diode works. A common additional material is an undisturbed layer of the basic semiconductor, called the inner layer. This is make -up PIN diodes.
The last part of the diode construction is the cathode. This connector is a coincidence for the anode. The cathode is metal, often copper and attracts negatively charged cations. This moves the power supply from the diode and to the connected system.
