The modern answer to this question is discussed in my recent paper
`What tells Gravity on the shape and size of an electron'' arXiv:1212.2920
Gravitational field of an electron, fixed by experimental values of its mass, spin, charge and magnetic moment, is given by the metric of Kerr-Newman (KN) solution. The spin of electron is very high and the black hole horizons disappear. So, it is over-rotating KN solution without horizons. Unexpectedly, this metric contains a singular ring of the Compton radius, which should be regulated resulting in a smooth metric of weak gravitational field. The regulated metric replaces the singular region by a source which has to be consistent with external KN metric, and the consistent source takes the form of a rotating vacuum bubble, bounded by a closed string of the Compton radius. This bubble is filled by a coherently oscillating Higgs field in the false vacuum state. The bubble at rest has the Compton size a=\hbar/2m, but the radius `a' shrinks sharply to a "point" when the electron acquires relativistic energies, as a consequence of the Kerr relation J=ma.

Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
What is the difference between the minority charge carriers and majority charge carriers in diodes?
Majority charge carriers in the N-type side of a semiconductor material are electrons, because N-type semiconductor is doped with a material with 5 valence electrons. Semiconductor materials have 4 valence electrons and hold tightly to 8, so there is a "loose" electron for every atom of dopant. Therefore most of the charge carriers available are electrons. IE, electrons are the majority charge carriers. Minority charge carriers in N-type semiconductor are holes. Only a few holes (lack of an electron) are created by thermal effects, hence holes are the minority carriers in N-type material. The situation is reversed in P-type semiconductor. A material having only 3 valence electrons is doped into the semiconductor. The semiconductor atoms have 4 valence electrons try to hold tightly to 8, so there is a virtual hole created by a "missing" electron in the valence orbit. This acts as if it were a positive charge carrier. Most of the charge carriers are these holes, therefore in P-type semiconductor holes are the majority charge carrier. Again, reverse situation to minority charge carriers. Some electrons are loosened by thermal effects, they are the minority charge carriers in P-type semiconductor.
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
Do both holes and electrons be regarded as the current producer?
No. They don't produce current, they only transport it.
How many holes does a flatworm have?
I have heard from the highest authority on flatworm holes that it's between 0 and infinite.
What is the difference between regular electrons and valence electrons?
electrons*
What is the difference between novel holes and the film of holes?
There is no difference, in the movie they used the same dialogue as they did in the book.

What is the two difference between 6C12 and 6C14?
electrons is the difference
What happends to electrons in a colvalent bond?
Electrons are shared between the atoms that are bonded. If there is an electronegativity difference between the atoms the electrons will be shared unequally.
Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
Whats the difference between electrons and protons?
Electrons have a negative charge and protons have a positive charge.

What is the difference in a game of golf and a round of golf?
There is no real difference between the two, between a round usually means playing 18 holes whereas a game could mean just 9 holes or more.
