Why do we use diode in electronic circuits?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking it in the opposite direction (the reverse direction)..
A diode is a two-terminal semiconductor device that allows current to flow through in one direction only. It basically has negligible resistance on one end and high resistance on another to prevent the current from flowing through both ways. Thus, a diode is like a valve in an electrical circuit.
Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They're like the one-way valve of electronics. If the voltage across a diode is negative, no current can flow*, and the ideal diode looks like an open circuit.
Diodes are made from two differently doped layers of semiconductor material that form a PN junction. The P-type material has a surplus of positive charge carriers (holes) and the N-type, has a surplus of electrons.
General Purpose Diodes are ideal for use in applications such as general-purpose switching, voltage clamping, reverse polarity protection, automotive, communication, UPS, battery chargers, welding, and traction.
The application areas of diodes include communication systems as limiters, clippers, gates; computer systems as logic gates, clampers; power supply systems as rectifiers and inverters; television systems as phase detectors, limiters, clampers; radar circuits as gain control circuits, parameter amplifiers, etc.
The diode allows the current to pass only in one direction. If the diodes are used in AC it will conduct only during half of the cycle. Thus they are used in the conversion of AC into DC. Hence, diodes are DC.

A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
A diode is used to block the electric current flow in one direction, i.e. in forward direction and to block in reverse direction. This principle of diode makes it work as a Rectifier. For a circuit to allow the current flow in one direction but to stop in the other direction, the rectifier diode is the best choice.

Practical physics application
Light-emitting diodes (LEDs) produce light by the recombination of electrons and electron holes in a semiconductor, a process called electroluminescence. The wavelength of the light produced depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, design features of the devices such as special optical coatings and die shape are required to efficiently emit light. A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide, and others, with various trace doping elements, are used to produce different colors of light. Another type of LED uses a quantum dot which can have its properties and wavelength adjusted by its size. Light-emitting diodes are widely used in indicator and display functions, and white LEDs are displacing other technologies for general illumination purposes.
