ABSTRACT:
A photosensitive element and a photosensitive device arrangement using the element include a charge transfer structure having an electrode layer extending over a photosensitive area of a semiconductor body. In operation, a bias potential is applied to the electrode layer to form a depletion layer in the underlying body portion, and a drift field is produced in the depletion layer which extends in the direction of an edge portion of the electrode layer to permit photogenerated charge carriers to be transmitted towards the edge portion. A preferred structure for producing the desired drift field includes a resistive electrode having first and second connections for applying a potential difference along the resistive electrode. The photosensitive device arrangement further includes a localized charge-storage zone adjacent the edge portion of the electrode layer for collecting the photogenerated charge carriers and a detector circuit for measuring the charge state of the charge-storage zone.
