What is semiconductor 12th class?
Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators (such as ceramics). Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon.
What is semiconductor in 12th Physics?
Semiconductor Diode/p-n Junction Diode A semiconductor diode is basically a p-n junction with metallic contacts provided at the ends for the application of an external voltage. The direction of arrow indicates the conventional direction of current (when the diode is under forward bias).

What is intrinsic and extrinsic semiconductor?
Intrinsic semiconductors are solely reliant on temperature while Extrinsic semiconductors are affected by temperature and the number of contaminants present. Intrinsic semiconductors are not further classified while N-type and p-type semiconductors are two types of semiconductors in Extrinsic semiconductors.
How many types of semiconductors are?
Types of Semiconductors: Semiconductors are divided into two categories: Intrinsic Semiconductor. Extrinsic Semiconductor.
How many types of semiconductors are there?
Semiconductors are divided into two categories: Intrinsic Semiconductor. Extrinsic Semiconductor.
What is the most basic semiconductor device?
Diode. A diode is a semiconductor device that comprises a single p-n junction.
What is n-type material?
An n-type semiconductor is an intrinsic semiconductor doped with phosphorus (P), arsenic (As), or antimony (Sb) as an impurity. Silicon of Group IV has four valence electrons and phosphorus of Group V has five valence electrons.
What is extensive and intensive semiconductor?
Intrinsic semiconductors are the pure form of semiconductor materials while extrinsic semiconductor materials are formed by adding some impurity to the pure semiconductors.
What is P-type and n-type semiconductor?
The majority carriers in a p-type semiconductor are holes. In an n-type semiconductor, pentavalent impurity from the V group is added to the pure semiconductor. Examples of pentavalent impurities are Arsenic, Antimony, Bismuth etc. The pentavalent impurities provide extra electrons and are termed as donor atoms.
