    Abstract: A sensor includes a first electrode and a second electrode, and a photo-active layer between the first electrode and the second electrode. The photo-active layer includes a light absorbing semiconductor configured to form a Schottky junction with the first electrode. The photo-active layer has a charge carrier trapping site configured to capture photo-generated charge carriers generated based on the light absorbing semiconductor absorbing incident light that enters at least the photo-active layer at a position adjacent to the first electrode. The sensor is configured to have an external quantum efficiency (EQE) that is adjusted based on a voltage bias being applied between the first electrode and the second electrode.

    Abstract: An image sensor may include a substrate, and a plurality of wavelength separation filters on the substrate and arranged along an in-plane direction of the substrate. The wavelength separation filters include a first wavelength separation filter configured to selectively transmit incident light in the first wavelength spectrum, and photoelectrically convert the incident light in at least one of the second wavelength spectrum or the third wavelength spectrum, a second wavelength separation filter configured to selectively transmit the incident light in the second wavelength spectrum and photoelectrically convert the incident light in at least one of the first wavelength spectrum or the third wavelength spectrum, and a third wavelength separation filter configured to selectively transmit the incident light in the third wavelength spectrum and photoelectrically convert the incident light in at least one of the first wavelength spectrum or the second wavelength spectrum.

    Abstract: An organic image sensor may be configured to obtain a color signal associated with a particular wavelength spectrum of light absorbed by the organic image sensor may omit a color filter. The organic image sensor may include an organic photoelectric conversion layer including a first material and a second material. The first material may absorb a first wavelength spectrum of light, and the second material may absorb a second wavelength spectrum of light. The organic photoelectric conversion layer may include stacked upper and lower layers, and the respective material compositions of the lower and upper layers may be first and second mixtures of the first and second materials. A ratio of the first material to the second material in the first mixture may be greater than 1/1, and a ratio of the first material to the second material in the second mixture may be less than 1/1.
