Determination of the Quantum Efficiency of a Light Detector
Kraftmakher, Yaakov
European Journal of Physics, v29 n4 p681-687 Jul 2008
The "quantum efficiency" (QE) is an important property of a light detector. This quantity can be determined in the undergraduate physics laboratory. The experimentally determined QE of a silicon photodiode appeared to be in reasonable agreement with expected values. The experiment confirms the quantum properties of light and seems to be a useful addition to other experiments on the photoelectric effect. (Contains 5 figures and 3 footnotes.)
