What is difference between electron and hole?

A hole can be seen as the “opposite” of an electron. Unlike an electron which has a negative charge, holes have a positive charge that is equal in magnitude but opposite in polarity to the charge an electron has. Holes can move from atom to atom in semiconducting materials as electrons leave their positions.

What is a hole in chemistry?

In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is the lack of an electron at a position where one could exist in an atom or atomic lattice. If an electron is excited into a higher state it leaves a hole in its old state.

Is hole a positron?

Hole is a quantum-mechanical counterpart of an electron. The important thing to remember is that a hole is not a positron, which is a fundamental particle having exactly same features as electron but opposite charge.

What is a hole in electricity?

In physics, a hole is an electric charge carrier with a positive charge, equal in magnitude but opposite in polarity to the charge on the electron. Holes and electrons are the two types of charge carriers responsible for current in semiconductor materials.

What is a hole in physics?

A hole is an absence of an electron in a particular place in an atom. Although it is not a physical particle in the same sense as an electron, a hole can be passed from atom to atom in a semiconductor material. Electrons and holes, both, are the charge carriers in any semiconductor substance.

How many amu is a proton?

1.007277 amu
mp = mass of a proton (1.007277 amu) mn = mass of a neutron (1.008665 amu)

Do holes have spin?

Yes, hole (missing electron) does have a spin. Consider a filled Fermi sea with all the electrons paired up so as to make zero total spin angular momentum.

What is the difference between an electron and a proton?

An electron is a negatively charged component of an atom whereas the proton is a positively charged body. The electrons are present outside the nucleus in the orbiting shells.

What is the difference between electron and hole and negative ion?

Electrons are subatomic particles that posses charge and can flow. While hole is a vacancy which is created after an electron leaves its place. And a negative ion is an atom that contains electrons more than the number of protons. Of course that has moved to it from some other atom.

What is the difference between a hole and a nucleus?

While hole generates from the electron leaving there places in valence band and moving to the conduction band. Hole has no charge and mass hence considered positive for caluculations while nucleus (proton) has positive charge and mass too.

Why are electrons highly mobile and proton are not?

Electrons are highly mobile as these are present in the shells of the atoms and can be easily freed on supplying energy. However, as the proton is present at the nucleus of the atom thus is not mobile like the electrons. The polarity of electrons is negative while that of the proton is positive.
