Abstract

A photo-sensitive device comprises: an active layer (116) configured to generate charges in response to incident light; a charge transport layer (114) arranged below the active layer (116), wherein the charge transport layer (114) comprises a first portion (114a) and a second portion (114b) being laterally displaced in relation to the first portion (114a); a gate (110) separated by a dielectric material (112) from the charge transport layer (114), wherein said gate (110) is arranged below the first portion (114a) and configured to control a potential thereof; and a transfer gate (122), which is separated by a dielectric material (112; 124) from a transfer portion (114b) of the charge transport layer (114) between the first portion (114a) and the second portion (114b), wherein the transfer gate (122) is configured to control transfer of accumulated charges in the first portion (114a) to the second portion (114b) for read-out of detected light.
