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 the energy band gap of barium titanate?
The energy band gap of barium titanate is approximately 3.2 electron volts (eV). This wide band gap makes barium titanate a good candidate for various applications in electronics and optoelectronics.
How electrons are jumping from one shell to other in the presence of forbidden zone of an atom?
may be electrons disappear from one shell when it receives it maximum energy and reappear at the other shell. or when the electrons receives it maximum energy it may convert into another form in band gap of an atom and again converted into its original form when it come it another shell which has fixed amount of energy...
Energy Band gap value for calcium carbonate and barium carbonate?
The energy band gap value for calcium carbonate (CaCO3) is around 5.6 eV, while for barium carbonate (BaCO3) it is approximately 6.3 eV. These values indicate the amount of energy required to promote an electron from the valence band to the conduction band in the respective materials.
Why energy gap is more in silicon than germanium?
The energy gap in silicon is larger than in germanium because of their different atomic structures. Silicon has a larger atomic size and a stronger atomic bond compared to germanium, leading to a wider energy gap between its valence and conduction bands. This larger energy gap in silicon results in better insulating properties and makes it a popular choice for high-performance electronics.
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, electrons cannot exist in the forbidden energy gap of a material. The forbidden energy gap is the energy range where no electron states can exist in a crystalline solid. Electrons can only occupy energy levels within the allowed energy bands of a material.
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
What is forbidden gap?
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.Avinash SinghJr. YSR (ISCA)Mech. Eng.KIIT UnivesityBBSR
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.

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.
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).
What is the difference between the energy gap of a semiconductor and a superconductor?
Energy gap in a superconductor is not a constant but depends on temperature. Energy gap in a semiconductor is a fixed quantity which does not depend on temperature. The excited quasiparticles or cooper pairs are produced two at a time hence the gap is 2Delta0. In a semiconductor the gap is the energy needed to excite 1 electron into the conduction band. The ground state in a superconductor is made of superconducting cooper pairs , above the gap the electrons are unpaired , the cooper pairs have lower energy. Conduction takes place in the lower ground state in Superconductors , where in semiconductors the electrons conduct from the conduction band. In a superconductor the gap is tied to the fermi level , while in a semiconductor it is fixed to the lattice in reciprocal space.
Does a small atom has more energy gap?
Energy gap depends on the energy of a particular energy level at a given radius in analogy with the energy of a hydrogen atom neing directly proportional to atomic number and inversely proportional to the square of nth energy level. It does not depend on the smallness of an atom.
Why intrinsic semiconductors behave like insulator at low temperature?
at low temperature its forbidden gap is very large so it act as a insulater.
