In a photodiode,the conductivity increases when the material is exposed to light.It is found that the conductivity changes only if the wavelength is less than 620nm.What is the band gap?

In a photodiode the coductivity increases when the material is exposed to light. It is found that coductivity change only if the wavelength is less than 600nm . What is the band gap?

In a photo diode the conductivity increases when the material is exposed to light. It is found that the conductivity changes only if the wavelength of incident light is less than 500 nm. What is the band gap? Use h=6.6xx10^(-34)Js, c=3xx10^(8) ms^(-1) .

When light falls on a photo diode, its conductivity increases. Experimetally it is found that the conductivity changes only when the wavelength of the incident light is less than 620 nm. The band gap of the diode is

Conductivity of a semiconuctor increases when a radiation of wavelength is less than 2480 nm is incident on it. The forbidden gap is

What will be the probability of electrons to be found in the conduction band of an intrinsic conductor at a finite temperature with increasing band gap?

The reverse-biased current of a particular p-n junction diode increases when it is expoesed to light of wavelength less than or equal to 600nm.Assume that the increases in carrier concentration takes place due to the creation of new hole-electron pairs by the light.Find the band gap.
