Photo Diode Sensor

Semiconductor photo devices utilize quantum effects on junctions, energies received by electrons that allow electrons to move from the valence tire to the conduction tire under reverse bias conditions. Semiconductor materials such as Germanium (Ge) and Silicon (Si) have 4 valence electrons, each electron in an atom is bonded so that the valence electron is even 8 for each atom, ...
