The invention comprises an optoelectronic platform with a carbon-based conduction layer (2) and a layer of colloidal quantum dots (1) on top as light absorbing material. The carbon-based conduction layer can be made of graphene, reduced graphene oxide, or carbon nanotubes. Photoconductive gain on the order of 106 is possible, while maintaining the operating voltage low. The platform can be used as a transistor.

Provided is an infrared light detector 100 wherein a light coupling mechanism 110 is configured by a metal thin film or metal thin plate in which a plurality of windows apart from each other are formed. Each of the windows is formed by multangular shapes in which a part of the internal angles are obtuse angles. The plurality of windows are periodically arrayed in postures having translational symmetry in at least two directions. The array cycle p of the plurality of windows are set according to a wavelength λ' of the infrared light of a substrate including a first electronic layer 110 so as to fall within a range with reference to a value at which a perpendicular oscillating electric field component in a first electronic region 10 indicates a peak value.

L'invention concerne un capteur d'images à semiconducteur à éclairement par la face arrière, dans lequel chaque cellule de photodétection comprend un corps semiconducteur (11) d'un premier type de conductivité d'un premier niveau de dopage délimité par un mur d'isolement (23, 24), des paires électrons-trous étant susceptibles de se former dans ledit corps par suite d'un éclairement par la face arrière ; du côté de la face avant dudit corps, un caisson annulaire (13) du deuxième type de conductivité, ce caisson délimitant une région sensiblement centrale (17) dont la partie supérieure (18) est du premier type de conductivité d'un second niveau de dopage supérieur au premier niveau de dopage ; et des moyens (V TG ; V wall ) de contrôle du transfert de porteurs de charge dudit corps vers ladite partie supérieure.
摘要:
A light shield (204) for blocking light traveling toward a PIN photodiode (413) from a glass substrate (314) side is formed of a conductive material, and a reference electric potential (Vr - nVoc) equal to that of a cathode of the PIN photodiode (413) is applied to the light shield (204) from a power supply circuit (266). Thus, inductive noise for a photoelectric conversion device used for an ambient light sensor is further reduced in a display device.
