Want this question answered?
the occupied highest band is the heavy band, the band prior below it is ligh band, the distance between two extremal points of those band is split-off band. At those points, hole is situated to be corresponding holes.
it is heavy
I am not aware of light calculating anything in a black hole.
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
If the ozone hole is big, the light will burn us. The light here is UV.
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.

exciton
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
A black hole has gravity so heavy it traps light.
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

It's what makes the light !
It emits light so is not "black". A "black hole" is a stellar body so massive that nothing can escape its gravity. Light actually consists of a stream of photons, so a sufficiently massive body can prevent light escaping from its surface. The sun, like most stars, is not massive, or heavy, enough to be a "black hole".
non heavy. light.
