How does motion of electron in n type substance differes from motion of hole in p type substance?

∙ 11y ago
Electrons constitute electronic current in n-type substance and holes constitute conventional current in p-type substance.The motion of electron in a n-type substance is opposite to that of holes in a p-type substance.

When an electron is displaced in a semiconductor the hole that left behind is?
A lack of electron
What is the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What are degenerate and non degenerate semiconductors?
Non degenerate semiconductors are those which: -are lightly doped -have less value of electron and hole concentration -violate Pauli's exclusion principle Degenerate semiconductors are those which: -are highly doped -have high value of electron and hole concentration -follow Pauli's exclusion principle
What are N type and p type substances?
p-TYPE SUBSTANCE:If a trivalent element from the IIIrd group such as Gallium (Ga) or Indium (In) is added to pure crystals of germanium (Ge) or silicone (Si), three electrons of impurity form covalent bonds with three atoms of (Ge) or (Si), while there exist a vacancy for an electron in the fourth bond. This vacant space is called Hole. This hole behaves like a positive charge and can move in the structure of substance. Such a substance is called a p-type substance.n-TYPE SUBSTANCE:If a pentavalent element from the Vth Group such as Antimony (Sb) is added to pure geranium (Ge) or silicone (Si), then four electrons of (Sb) will form covalent bonds with four (Ge) or (Si) atoms. The fifth electron of 'Sb' is free to move which makes (Ge) or (Si) a good conductor. This type of material is called n-type substance.Reference: http://www.citycollegiate.com/electronicsXa.htm
Is IGBT the bipolar device?
IGBT and BJT are bipolar devices as the name suggest. Meaning of bipolar device both electrons and holes leads to current unlike FET where either electron or hole causes current.
What is oxidizing substance?
your mums hole
How the hole moves?
A hole is a place where an electron is missing. If an electron moves into that places, the electron will be missing somewhere else - the hole has moved along.A hole is a place where an electron is missing.

What is need to study about hole curren when there is actually electron current which is involved?
actually it is the holes which lead to the movement of the electron,as electron moves to the hole's place creating a hole behind.
Why hole has positive charge?
A hole is a place where an electron is missing. Since the electron has a negative charge, the lack of an electron produces a net positive charge.
When an electron is displaced in a semiconductor the hole thats left behind is what?
When an electron is displaced in a semiconductor, the hole that is left behind is called an electron hole. Energy can still be conducted because other electrons can and do jump to the space left by a displaced electron.

A lack of electron
What is an oxidizing substance?
An oxidisable substance is anything that is able to combine with oxygen. That includes anything that can burn or rust.
What is the mass of electron hole?
Simply, that's because in most semiconductor materials when an electric field is applied the holes have lower mobility than that of the electrons which means the hole effective mass is larger than the electron effective mass. And you can clearly see the effect of that in semiconductor nanocrystals (or as they called sometimes "quantum dots"), the energy levels in the conduction band are further apart than what they are in the covalent band due the fact that the effective hole mass is larger .... Good luck Physics PhD student, University of Toledoooo!
Differnce between holes and electron?
Electron: It is a negative charged elementary particle. Hole: The vacant seat of electron is called hole. It can attract an electron jumping to holes. Therefore, location of holes keep changing. it is not an ion because it is created without the removal of electron.
What is a bound hole electron pair in a semiconductor?
exciton
What will be the motion of water in the tank when small hole is created at the bottom?
The motion of water will be spherical.
The merging of a free electron and a hole is called?
This is called "Recombination"
