  • Abstract
    The influence of the place and the number of the peripheral ohmic contacts on the characteristics of a light-spot-position-sensitive photodiode based on the lateral photoeffect is investigated. Using contact pairs, a 9·3×9·3 mm2 photodiode shows a 6×6 mm2 linear area in which the x- and y-signals unambiguously depend on the co-ordinates. An extra contact ring makes it possible to make the cell light-intensity independent.
