It sounds like a math trick because the electron cannot exist in the middle of the band gap. The trick would be that it would take an infinite amount of energy to excite the electron to the middle of the band gap.

What is the natural frequency of a material?
it is the square root of the ratio of the effective stiffness to the effective mass of the body. vVery difficult to obtain due to the infinite degrees of freedom the human body has.
Does a black hole have infinite mass?
No, a black hole definitely does not have infinite mass. In some mathematical models, there is an object called a singularity, inside a black hole, which has infinite density. That is not the same as infinite mass. If a finite mass is contained in zero volume, then the density becomes infinite. We do not have any real confirmation that such a thing as a singularity or an infinite density actually exist, but they may.
What should be the mass of anything at the speed of light?
Anything that has any mass when it's at rest would have infinite mass at the speed of light.
Why is the speed of light not higher?
The particle that is light is called the Photon. The photon is massless and can travel faster than any other particle because it has no mass. Any particle that has mass will require infinite energy to reach the velocity of light, which is impossible because the particle will have infinite mass in the process (Remember E=mc^2).
How do you calculate equivalent equation for carbon dioxide?
Effective mass, or m*, is the mass that a compound seems to have when responding to external forces. Determination of the effective mass is usually done via cyclotron resonance.
Why effective mass of electron is negative at the top of valence band?
Because of holes

Is it more correct to say that a Black Hole has infinite mass or infinite gravity?
A black hole has infinite density.
Is it true holes have a mass?
The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.
How much muscle mass does Ben Affleck have?
infinite.
What happens if you move at the speed of light?
You would have infinite mass and infinite length. From your perspective, you would get to your destination in zero time.If you have finite mass now, it would require infinite energy to attain the speed of light, so this can never happen.
What is the difference between rest mass and effective mass of electron?
mass
Why is Water dense?
because it has a heavy mass but infinite volume
What is interesting about a black hole?
I has infinite mass but zero volume.
Light has mass then why doesnt emc2 matter. The mass should become infinite and E infinite?
Okay....well that's why light does not have mass, or rather if it did, then it could not travel at the fundamental speed limit "c". This is a key to understanding the universe.
