Patent ID: 10446771

Abstract:
According to one embodiment, a radiation detector includes first, and second conductive layers, and an organic layer. The organic layer is provided between the first and second conductive layers. A first thickness of the organic layer along a first direction from the second conductive layer toward the first conductive layer is 1 μm or more. The organic layer includes a first compound of a first conductivity type, and a second compound of a second conductivity type. A first value of (0.9·λ)/(w1·cos θ1) for a first peak of X-ray analysis of the organic layer is not less than 13 nm and not more than 19 nm. The first value is obtained from a first Bragg angle θ1 (radians), a first full width at half maximum w1 (radians) of the 2θ1 peak, and an X-ray wavelength λ (nm). The 2θ1 is not less than 0.0750 radians and not more than 0.1100 radians.
