Conductivity on semiconductors - Coggle Diagram
Conductivity on semiconductors
Conductivity: is the measure of the ease at which an electric charge or heat can pass through a material.
The engineered conductivity is used in order to create the conduction of electrical charges in a material
Energy to ionized
With this formula is possible to move an electron from valence band to conduction band
Semiconductor: any of a class of crystalline solids intermediate in electrical conductivity between a conductor and an insulator. Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits.
7 crystal Systems
Orthormbic
Trigonal
Hexagonal
Triclinic
Tetragonal
Monoclinic
Cubic
The specific properties of a semiconductor depend on the impurities, or dopants, added to it.
Materials N-Type: An N-type semiconductor carries current mainly in the form of negatively-charged electrons, in a manner similar to the conduction of current in a wire. Donor dopant
eg: Arsenic, phosphorus, bismuth, antimon. These elements counts with 5 electrons in valence band
With this materials is possible to create a PN junction, most known as diode.
When the p-type is connected to the positive terminal of the battery and the n-type to the negative terminal then the p-n junction is said to be forward-biased
When the p-type is connected to the negative terminal of the battery and the n-type is connected to the positive side then the p-n junction is said to be reverse biased.
Behavior Graph
P-type semiconductor carries current predominantly as electron deficiencies called holes. A hole has a positive electric charge, equal and opposite to the charge on an electron. In a semiconductor material, the flow of holes occurs in a direction opposite to the flow of electrons. Acceptor dopant
eg: Boron, Indium, Gallium. These elements counts with 3 electrons in valence band
