Electronics
When the p-type and n-type semiconductors combine, they make a diode. There are two types of diodes, p-n-p and n-p-n.
p-n junction diode: A PN Junction Diode is one of the simplest semiconductor devices around, and which has the characteristic of passing current in only one direction only.
-
p-n junction: a boundary between p-type and n-type material in a semiconductor device, functioning as a rectifier.

Extrinsic semiconductors
Artificially manufactured by adding impurities in intrinsic semiconductors to increase the conduction
Types
p-type semiconductor: when tri-valent impurity is added in intrinsic semiconductor. 
n-type semiconductor: when penta-valent impurity is added in intrinsic semiconductor.

Rectification: A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction
Full wave rectification: a rectifier that converts alternating current into continuous current and that utilizes both halves of each cycle of the alternating current.
Half wave rectification: a type of rectifier that allows only one-half cycle of an AC voltage waveform to pass while blocking the other half cycle
Transistor: A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
P-N-P transistor: The transistor in which one n-type material is doped with two p-type materials. It is a current controlled device. The PNP transistor has two crystal diodes connected back to back. The left side of the diode in known as the emitter-base diode and the right side of the diode is known as the collector-base diode.
N-P-N transistor: The transistor in which one p-type material is placed between two n-type materials. It amplifies the weak signal enter into the base and produces strong amplify signals at the collector end. In it, the direction of movement of an electron is from the emitter to collector region due to which the current constitutes in the transistor.
Direct current is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators
Reverse bias: It reinforces the potential barrier and impedes the flow of charge carriers. Forward bias decreases a diode's resistance, and reverse bias increases a diode's resistance. The current flows effortlessly while in forward bias, but reverse bias does not permit current to flow through the diode
Forward bias is where the external voltage is delivered across the P-N junction diode. In a forward bias setup, the P-side of the diode is attached to the positive terminal and N-side is fixed to the negative side of the battery.
