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.
What is energy gap?
there will be only certain energy levels in which electrons get filled up. In valence orbitals there will be many such energy levels and the energy gap between conduction band and valence band is called energy band gap.
What is the forbidden energy gap?
The forbidden energy gap refers to the energy range within a material where electron states are not allowed to exist. This gap prevents electrons from moving freely and conducting electricity. Materials with larger forbidden energy gaps are typically insulators, while materials with smaller gaps or none are conductors or semiconductors.
Why effective mass is infinite at the middle of the band gap?
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 happen to the band gap energy when zinc doped to copper oxide thinfilms?
3.6 to 3.5 may be

What is the energy band gap of germanium?
The energy band gap of germanium is approximately 0.67 electronvolts (eV). This means that it requires this amount of energy to move an electron from the valence band to the conduction band in germanium.
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 are the difference between direct and indirect band gap materials?
In a direct band gap the electron only needs energy to jump to the conduction band. In an indirect band an electron needs energy and momentum to jump to the conduction band
What is the band gap energy in si and ge?
at 300 Kelvin, silicon band gap is 1.11 eV, Germaium band gap is 0.66 eV.source: hyperphysics.phy-astr.gsu.edu/hbase/Tables/Semgap.html
What is the difference between direct and indirect energy?
The band gap represents the minimum energy difference between the top of the valence band and the bottom of the conduction band, However, the top of the valence band and the bottom of the conduction band are not generally at the same value of the electron momentum. In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum.In an indirect band gap semiconductor, the maximum energy of the valence band occurs at a different value of momentum to the minimum in the conduction band 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.
What type of oil is used in energy band gap?
the stewpid kined
What is the energy band gap for germanium?
The energy band gap for germanium is around 0.67 electron volts (eV) at room temperature. This makes germanium a semiconductor with properties in between those of conductors and insulators.
According to band theory mg is an insulator while in practice it is a conductor why?
According to band theory , the energy gap between valence band and conduction band was high. But during heating the energy gap get decreased. this is the reason why the mg behaves as an conductor.
What is band gap of electrolyte (Na2SO4)?
The band gap of an electrolyte like Na2SO4 is not well-defined as it consists of ionic compounds which do not have a band structure like semiconductors. Band gap is a property of materials with covalent bonding, like semiconductors, where it represents the energy difference between the valence and conduction bands.
What is the value of band gap of zinc selenide?
The band gap of zinc selenide is approximately 2.7 electron volts (eV). This value indicates the energy difference between the valence band and the conduction band in the material. Zinc selenide is a semiconductor commonly used in optoelectronic applications due to its wide band gap.
