    The first documented observation of a semiconductor effect is that of Michael Faraday (1833), who noticed that the resis- tance of silver sulfide decreased with temperature, which was different than the dependence observed in metals [2]..

  • Who made semiconductor electronics?

    In 1874, Karl Braun discovered and documented the first semiconductor diode effect.
    Braun observed that current flows freely in only one direction at the contact between a metal point and a galena crystal.
    In 1901, the very first semiconductor device, called "cat whiskers," was patented..

  • An n-type semiconductor is an intrinsic semiconductor doped with phosphorus (P), arsenic (As), or antimony (Sb) as an impurity.

A semiconductor is a substance that has specific electrical properties that enable it to serve as a foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not others.
A semiconductor substance lies between the conductor and insulator. It controls and manages the flow of electric current in electronic equipment and devices. As a result, it is a popular component of electronic chips made for computing components and a variety of electronic devices, including solid-state storage.

Creation of Hole

Due to the thermal energy supplied to the crystal, some electrons tend to move out of their place and break the covalent bonds. These broken covalent bonds, result in free electrons which wander randomly. But the moved away electrons creates an empty space or valence behind, which is called as a hole. This hole which represents a missing electron c.

Hole Current

It is already understood that when a covalent bond is broken, a hole is created. Actually, there is a strong tendency of semiconductor crystal to form a covalent bond. So, a hole doesn’t tend to exist in a crystal. This can be better understood by the following figure, showing a semiconductor crystal lattice. An electron, when gets shifted from a.

Intrinsic Semiconductors

A Semiconductor in its extremely pure form is said to be an intrinsic semiconductor. The properties of this pure semiconductor are as follows −.
1) The electrons and holes are solely created by thermal excitation.
2) The number of free electrons is equal to the number of holes..
3) The conduction capability is small at room temperature. In order to i.
