Which is NOT related to the fabrication of a semiconductor device.

. The addition of trivalent impurities such as boron aluminum or gallium to an intrinsic semiconductor creates these positive electron holes in the structure. Log in for more information. Electrons are the majority charge carriers in n-type.

It uses phosphorus so that electrical conduction is due to the movement of electrons-best describes an example of an n-type semiconductor. Classify each of the following as being either a p-type or an n-type semiconductor i Ge doped with In ii B doped with Si. P-type semiconductor refers to positive type doping of semiconductor.

Due to this combination a large number of holes are created in it. Which best describes an example of a p-type semiconductor. 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.

Hence option B is correct answer. Which best describes an example of a p-type semiconductor. Boron B Gallium Ga Indium In Aluminium Al etc are trivalent impurities.

The majority carriers in a p-type semiconductor are holes. When a trivalent impurity like Boron Aluminum etc is added to an intrinsic or pure semiconductor silicon or germanium it is said to be a p-type semiconductor. The trivalent impurity used for doping purpose of a p-type semiconductor are boron gallium and indium.

In an n-type semiconductor pentavalent impurity from the V group is added to the pure semiconductor. A p-type semiconductor is an extrinsic type of semiconductor. It uses boron so that electrical conduction is due to the movement of a positive charge.

Therefore Ge doped with In will generate p-type semiconductor. In a p-type semiconductor a large number of holes are created by the trivalent impurity. The holes are available in the valence band are directed towards the negative terminal.

For example a silicon crystal doped with boron group III creates a p-type semiconductor whereas a crystal doped with phosphorus group V results in an n-type semiconductor. When a potential difference is applied across this type of semiconductor as shown in the figure below. Examples of p-type semiconductors are silicon doped with gallium and silicon doped with boron.

Type of concentration added. Trivalent impurities such as boron B gallium Ga indium In aluminum Al etc. I Ge is a 14 th group element and In is a 13 th group element.

Answer Dit uses boron so that electrical conduction is due to the movement of positive charge. Added 162020 102436 AM. An electron deficit hole created when 14 th group element is doped with 13 th group element.

As the current flow through the crystal is by holes. Which best describes an example of a p-type semiconductor. There are two types of semiconductors ie.

The pentavalent impurities provide extra electrons and are termed as donor atoms. P-type is a type of semiconductor that is formed when a trivalent impurity is added to an intrinsic semiconductor like silicon or germanium. That is why we consider holes as majority carriers and electrons are called minority carriers in a p-type semiconductor.

A semiconductor substance lies between the conductor and insulator. Examples of pentavalent impurities are Arsenic Antimony Bismuth etc. While teaching about transistors Mrs.

Hence the number of free electrons in a p-type semiconductor is much smaller than the number of holes in it. Correct option is B In p-type semiconductor an intrinsic semiconductor is doped with trivalent impurities that creates deficiencies of valence electrons called holes which are majority charge carriers. Are called acceptor impurity.

Why are semiconductors valuable in modern electronics. Conduction Through p-Type Semiconductor. It controls and manages the flow of electric current in electronic equipment and devices.
