Abstract
The present invention relates to an optoelectronic apparatus, comprising: —an optoelectronic device comprising: —a transport structure (T) comprising a 2-dimensional layer; —a photosensitizing structure (P) to absorb incident light and induce changes in the electrical conductivity of the transport structure (T); and—drain (D) and source (S) electrodes electrically connected to the transport structure (T); —a read-out unit to read an electrical signal, generated at a transport channel of the transport structure (T), after an integration time interval tint has passed, and during a taccess that is at least 10 times shorter than tint, wherein tint is longer than a predetermined trapping time τtr. The present invention also relates to a reading-out method, comprising performing the operations of the read-out unit of the apparatus of the invention, and to the use of the apparatus as a light detector or as an image sensor.
