A semiconductor is a material that has electrical conductivity that falls between that of conductors and insulators. It is used in a wide range of electronic devices, including computers, smartphones, and other consumer electronics, as well as in industrial, medical, and military applications.

Semiconductors work by controlling the flow of electrical current through a circuit. They do this by using the movement of electrons, which are tiny particles with a negative electrical charge. In a semiconductor, the electrons are able to move freely within the material, but they are not able to move as freely as they can in a conductor, such as copper.

Semiconductors are made from a variety of materials, including silicon, germanium, and other elements from the periodic table. These materials are carefully purified and treated to create a crystal structure that allows the electrons to move freely within the material.

The electrical conductivity of a semiconductor can be controlled by adding impurities, or “dopants,” to the material. By adding impurities that have extra electrons, such as phosphorus, the semiconductor becomes more conductive, making it easier for the electrons to flow. This type of semiconductor is known as an n-type semiconductor. On the other hand, if impurities that are missing electrons, such as boron, are added to the semiconductor, it becomes less conductive, making it harder for the electrons to flow. This type of semiconductor is known as a p-type semiconductor.

Semiconductors are used in a variety of ways in electronic devices. For example, they can be used to amplify signals, as in an amplifier, or to switch electrical current on and off, as in a transistor. They are also used in solar cells to convert sunlight into electricity, and in LED lights to produce light.
