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) configured and arranged 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 respective separate locations of the transport structure (T); —noise suppression means comprising a modulation unit including: —a control unit to generate and apply on the drain (D) or source (S) electrodes a voltage oscillating signal having a component with a frequency of ω/2π; and —a signal extraction unit to extract a required electric signal, from an output signal, with no components below ω/2π. The present invention also concerns to a method for suppressing noise for an optoelectronic apparatus according to the invention, and to the use of the apparatus as a light detector or as an image sensor.
