And to get back to the original question: on the surface of the Si photodiode the SiO2 coating should change the visible light's wavelength too based on the above mentioned optical equations. Is there an other medium between the photodiode and the SiO2 layers in which the light's wavelength...
Yes I am in control of the source and the subject can withstand the IR radiance, though inducing two photon fluoresence does change the energy of a single photon?
Thank you for the great article and explanation rbelli1 and Drakkith. What do you think is there any way to increase somehow the energy of a single photon or a beam of photons higher than the band gap energy to make them energized enough to cause photoelectric effect in Si?
Dear friends I am new at this forum thank you for accepting my application first of all.
My question is that I don't understand the optics/physics behind the reason why Si-based CCDs are not sensitive for IR-light (above 1000-1100 nm) if on the top of the p-type Si there is a SiO2 layer which...
