When atoms are brought close together, as in a solid, the electrons come under the influence of forces from other atoms, where the energy level merges into bands of energy levels. There are two distinct energy bands in which electrons could exist: the valence band and the conduction band . Separating these two bands is an energy gap , termed the forbidden gap, in which electrons cannot normally exist.

Why intrinsic semiconductors behave like insulator at low temperature?
at low temperature its forbidden gap is very large so it act as a insulater.
What is the resistance of an air gap?
The resistance of an air gap is effectively infinite until it reaches its arcover threshold voltage; then it drops to near zero as the air in the gap ionizes. It returns to effectively infinite when the current through the gap is insufficient to keep the air ionized.
What is specific magnetic loading?
Specific magnetic loading is ratio average flux air gap and flux path of air gap:
What is meant by Horn Gap Fuse?
horn gap fuse is a protective device which use to protect the equipment from higher voltage.actually horn fuse or horn gap fuse is a thin wire element as compare to load line when a high current drawn in line the wire is melt and line protect.
What is the band gap of carbon?
C is a conductor, so valence and conduction bands overlap. if you mean SiC, silicon carbide, energy gap is ~2.86eV @ 300K (ambient temperature)
What is the forbidden gap of gallium?
5
What is forbidden energy?
The gap in energy that you are forbidden from visiting. It's a government conspiracy.
Do you find electrons in forbidden energy gap?
no
What is the forbidden energy gap?
it is the energy required to transfer an electron from valence band to conduction band, the external energy which is required is equal to the forbidden energy gap
Is it possible to have an energy level in the forbidden gap?
Yes. In quantum mechanics, "forbidden" often means "unlikely" and not actually "no way, no how."
What is a difference between forbidden energy gap depletion region in semiconductor?
forbidden energy gap or energy gap or band gap or band or Eg is the gap between the top of the valance band and bottom of the conduction band. If we apply the energy equivalent to Eg then the electrons in valance band will jump to the conduction band. Ravinder kumar meena stpi n depletion region is the region in semiconductor where there is depletion of free charge carriers.Ravinder kumar meena stpi n
Titanium dioxide is direct band gap or indirect band gap material?
Yes it is. Most Sn (tin) materials as semiconductors are direct band gap materials. Silicon on the other hand is an indirect band gap material.
Why intrinsic semiconductors behave like insulator at low temperature?
at low temperature its forbidden gap is very large so it act as a insulater.
How you explain on atomic level that capacitor block dc?
Potential barriers. Insulators have a large band gap (forbidden gap) such that both electrons and holes have to possess enormous energy in order to have a chance to cross the barrier to the other side (DC blocking).
When an electron in the ground state absorbs energy what happens?
jumps to the a higher orbital. This is only possible if the energy it absorbed is large enough to let it jump the gap. If the energy is not large enough for the electron to jump that gap, the electron is forbidden to absorb any of that energy.
What is a sentence with the word forbidden?
The Forbidden Kingdom is huge.She was forbidden from seeing him again.Swearing in public is forbidden.
How do you spell forbidden?
Forbidden
