A cross sectional view of the laser diode having an anode and cathode to allow injection.

Diode fabrication definition. P and n type impurities can be alternately added to the molten semiconductor material in the crucible which results in a p n junction as shown when crystal is pulled. Varactor diode is a pn junction diode that is especially operated in reverse biased mode. A schottky diode is a 2 terminal metal semiconductor device that is formed by diffusing an n type semiconductor over a metal.

Electrically the semiconductor laser diode is a pn junction diode. Negative charges electrons can easily flow through the junction from n to p but not from p to n and the reverse is true for holes. Diodes are widely used semiconductor device.

It is a device whose capacitance varies with the variation in the applied reverse bias potential. Fabrication techniques of a p n junction diode. A diode is a specialized electronic component with two electrodes called the anode and the cathode.

Both metal and n type semiconductor have electrons as their majority carriers as almost negligible holes are present in a metal. The word varicap is derived from the combination of word variable and capacitor. An ideal diode will have zero resistance in one direction and infinite resistance in the reverse direction.

A pn junction diode allows electric charges to flow in one direction but not in the opposite direction. The fabrication of the transistor is the process of creating the transistor that is used in electrical and electronics circuit. Generally p n junction diode is formed by joining together n type and p type semiconductor materials.

Some diodes are comprised of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure. It is also known as varicap or voltcap. Diodes of this type are formed during the crystal pulling process.

Most diodes are made with semiconductor materials such as silicon germanium or selenium. A rectifier diode is a two lead semiconductor that allows current to pass in only one direction. Of current into the intrinsic layer i layer active region 2.

A diode is defined as a two terminal electronic component that only conducts current in one direction so long as it is operated within a specified voltage level. The p type side is called the anode and the n type side is called the cathode. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes a heated cathode and a plate in which electrons can flow in only one direction from cathode to plate.
