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 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.
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 the significance of the optical band gap in the study of semiconductors?
The optical band gap is important in the study of semiconductors because it determines the energy required for electrons to move from the valence band to the conduction band, allowing them to conduct electricity. This gap influences the semiconductor's ability to absorb and emit light, which is crucial for various electronic applications such as solar cells and LEDs.
What is the narrow-band semiconductor?
A narrow-band semiconductor is a type of semiconductor material with a small energy gap between its valence band and conduction band. This small energy gap allows for electrons to move easily between the bands, making it suitable for applications such as optoelectronics and telecommunications.
What happen to the band gap energy when zinc doped to copper oxide thinfilms?
3.6 to 3.5 may be
What is the value of band gap for thermistor?
NTC thermistors are metal oxide which has energap gap of the oder 0.5eV
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 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
What is the highest band gap value for semiconductors?
Fairly certain Beryllium Oxide is an extrinsic semiconductor with band gap 10.6 eV. Otherwise the answer is Boron Nitride (6.36 eV)
When was The Gap Band created?
The Gap Band was created in 1967.
Is ZnSe is direct or indirect band gap?
It is direct band gap material.
When was Gap Band IV created?
Gap Band IV was created in 1981.
When was The Gap Band II created?
The Gap Band II was created in 1979.
When was The Gap Band III created?
The Gap Band III was created in 1980.
What does gap stand for in the gap band?
greenwood archer and pine street band
Why Zinc oxide is a semiconductor?
A substance is classified as a good/bad/semi conductor based upon the energy gap (band gap) in between the valence bands and conduction bands (which are nothing but the collection of molecular orbital energy levels). for ZnO the band gap is ~3.4eV (electron volts). this value is more than for a conductor (like most of the metals Cu, Zn, Ag, Au etc) and less than bad conductors (Wood, Paper etc). so ZnO is a semi conductor. these type of materials can be played with to behave as a good or bad conductor.
