Jt. Sheridan et al., INCREASING THE EFFICIENCY OF MSM DETECTORS USING A DIFFRACTION GRATING, Measurement science & technology, 4(12), 1993, pp. 1525-1527
It is shown that the efficiency of metal-semiconductor-metal (MSM) det
ectors can be improved using a dielectric diffraction grating, positio
ned appropriately above the detector. The grating has the effect that
the light is channelled into the grooves between the metallic electrod
es. In this way the efficiency is increased relative to a conventional
MSM detector.
