  2. Semiconductor material types

Absolute zero

Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.

See Intrinsic semiconductor and Absolute zero

Charge carrier

In solid state physics, a charge carrier is a particle or quasiparticle that is free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors.

See Intrinsic semiconductor and Charge carrier

Charge carrier density

Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume.

See Intrinsic semiconductor and Charge carrier density

Crystallographic defect

A crystallographic defect is an interruption of the regular patterns of arrangement of atoms or molecules in crystalline solids.

See Intrinsic semiconductor and Crystallographic defect

Dopant

A dopant (also called a doping agent) is a small amount of a substance added to a material to alter its physical properties, such as electrical or optical properties.

See Intrinsic semiconductor and Dopant

Electrical resistivity and conductivity

Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current.

See Intrinsic semiconductor and Electrical resistivity and conductivity

Electron

The electron (or in nuclear reactions) is a subatomic particle with a negative one elementary electric charge.

See Intrinsic semiconductor and Electron

Electron excitation

Electron excitation is the transfer of a bound electron to a more energetic, but still bound state.

See Intrinsic semiconductor and Electron excitation

Electron hole

In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice.

See Intrinsic semiconductor and Electron hole

Excited state

In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum).

See Intrinsic semiconductor and Excited state

Extrinsic semiconductor

An extrinsic semiconductor is one that has been doped; during manufacture of the semiconductor crystal a trace element or chemical called a doping agent has been incorporated chemically into the crystal, for the purpose of giving it different electrical properties than the pure semiconductor crystal, which is called an intrinsic semiconductor. Intrinsic semiconductor and extrinsic semiconductor are semiconductor material types.

Introduction to Solid State Physics

Introduction to Solid State Physics, known colloquially as Kittel, is a classic condensed matter physics textbook written by American physicist Charles Kittel in 1953.

See Intrinsic semiconductor and Introduction to Solid State Physics

Mercury cadmium telluride

Hg1−xCdxTe or mercury cadmium telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions.

See Intrinsic semiconductor and Mercury cadmium telluride

P–n junction

A p–n junction is a combination of two types of semiconductor materials, p-type and n-type, in a single crystal.

See Intrinsic semiconductor and P–n junction

Semiconductor

A semiconductor is a material that has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass.

See Intrinsic semiconductor and Semiconductor

Vacancy defect

In crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites.

See Intrinsic semiconductor and Vacancy defect

Valence and conduction bands

In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of the solid.
