Why is conductivity of doped n-type semiconductor higher than that of pure semiconductor?

n-type semiconductor contains an increased number of electrons in the conduction band. Therefore, Si doped with P has more number of electrons in the conduction band than those in the conduction band in pure Si. Thus, the conductivity of Si-doped with P is higher than that of pure Si.

Is N type more conductive than p-type?

since electron has high mobility compared to hole, conductivity of n-type semiconductor material is greater than p-type semiconductor.

What are n-type semiconductor Why is the conductivity of n-type semiconductor higher than that of pure semiconductor explain with diagram?

N-type semiconductors are those conductors that have a pentavalent impurity and have 5 electrons in their valence shell. Explanation: The conductivity of the N-type semiconductor is higher than the pure semiconductor because it has more number of dopant elements.

Which has more electric conductivity between p-type and n-type semiconductor and why?

But in extrinsic semiconductors, which is doped with a p-type or n-type impurity to form p-type and n-type semiconductor so as to increase the number of holes or number of electrons in a semiconductor respectively. More the charge carriers, more is the conductivity.

Which type of semiconductor is best?

Silicon is the most widely used type of semiconductor material. Its major advantage is that it is easy to fabricate and provides good general electrical and mechanical properties.

What is n-type semiconductor with diagram?

A N-type semiconductor is created by doping this pure silicon crystal lattice with a pentavalent impurity element like Antimony (Sb). In an N-type semiconductor the atom of pentavalent impurity element Antimony (Sb) is in between silicon atoms. The Silicon atoms have four electrons in the valence shell.

What is n-type semiconductor?

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. * This free electron is the carrier of an n-type semiconductor.

Why is p type semiconductor more conductive than n type?

The formation of electrons in this semiconductor is called as acceptors. The conductivity of p-type is because of the presence of majority charge carriers like holes. The conductivity of n-type is because of the presence of majority charge carriers like electrons.

What makes an intrinsic semiconductor an n type semiconductor?

The N-type semiconductor can be defined as, once the pentavalent impurity atoms such as Sb, As is added to an intrinsic semiconductor, and then it is known as an n-type semiconductor. In this semiconductor, the majority charge carriers are electrons whereas minority charge carriers are holes.

How does a semiconductor behave at low temperature?

The semiconductor has filled valence band, empty conduction band, and small energy gap or Forbidden gap between valence and conduction band. Semiconductors virtually behave as an insulator at low temperature. However, even at room temperature, some electron cross over to the conduction band, imparting little conductivity.

Which is the majority charge carrier in a semiconductor?

In this semiconductor, the majority charge carriers are holes whereas minority charge carriers are electrons. The hole’s density is higher than the electrons density. The accepts level mainly lies nearer to the valence band.
