Abstract
An imaging apparatus includes a semiconductor substrate; a first electrode; a second electrode; a photoelectric conversion layer disposed between the first electrode and the second electrode, and including a donor organic semiconductor material and an acceptor organic semiconductor material; a charge accumulation node positioned within the semiconductor substrate and electrically connected to the second electrode; and a first blocking layer disposed between the first electrode and the photoelectric conversion layer. The photoelectric conversion layer has an ionization potential of lower than or equal to 5.3 eV. The first blocking layer has an electron affinity lower than an electron affinity of the acceptor organic semiconductor material included in the photoelectric conversion layer. The imaging apparatus has spectral sensitivity in a near-infrared light region having wavelengths of greater than or equal to 650 nm and less than or equal to 3000 nm.
