What is p-type semiconductor with diagram?

What is p-type semiconductor with diagram?

Definition: Once the trivalent material is given to a pure semiconductor (Si/Ge) is known as a p-type semiconductor. Here, trivalent materials are Boron, Indium, Gallium, Aluminium, etc. Most frequently, semiconductors are made with Si material as it includes 4 electrons in its valence shell.

Which energy level is created in a p-type semiconductor?

P-type because of majority a-holes it referred to as a positive type. As it is a p-type semiconductor the Fermi level is present near to the valence band rather than conduction band.

How are p-type and n-type semiconductor formed draw energy band diagram?

Draw the energy band diagrams of p-type and n-type semiconductors. A semiconductor has equal electron and hole concentration 6 x 108 m–3. On doping with a certain impurity, electron concentration increases to 8 x 1012 m–3. Identify the type of semiconductor after doping….Semiconductor Electronics: Materials, Devices and Simple Circuits.

What is p-type semiconductor?

A p-type semiconductor is an extrinsic type of semiconductor. 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. Trivalent impurities such as boron (B), gallium (Ga), indium (In), aluminum (Al) etc.

What is p-type semiconductor Class 12?

(ii) p-type semiconductors: When a pure semiconductor is doped with a trivalent impurity (B, Al, In, Ga ) then, the three valence electrons of the impurity bond with three of the four valence electrons of the semiconductor. This makes a vacant electron (hole) in the impurity atom.

How does p-type semiconductor conduct electricity?

p-type semiconductors are characterized by a deficit of electrons and positive holes, which have the same effect as a surplus of positive charge. These positive holes accept electrons, rendering the semiconductor more effective at conducting current.

How is p-type semiconductor formed?

P-type semiconductors are created by doping an intrinsic semiconductor with an electron acceptor element during manufacture. The term p-type refers to the positive charge of a hole. As opposed to n-type semiconductors, p-type semiconductors have a larger hole concentration than electron concentration.

What is p-type semiconductor 11th class?

In a p-type semiconductor, trivalent impurity from the III group elements is added as the impurity. Trivalent impurities like Aluminium, Indium and Gallium are added to the intrinsic semiconductor. The trivalent impurities added provides extra holes known as the acceptor atom.
