Abstract: A radiation detector includes a substrate including a first electrode portion, a radiation absorption layer disposed on one side with respect to the substrate and configured of a plurality of perovskite crystals, and a second electrode portion disposed on the one side with respect to the radiation absorption layer and being opposite to the first electrode portion with the radiation absorption layer interposed therebetween. Each of the plurality of perovskite crystals is formed to extend with a first direction in which the first electrode portion and the second electrode portion are opposite to each other as a longitudinal direction in a region between the first electrode portion and the second electrode portion in the radiation absorption layer.

Abstract: A smell sensor includes an ion sensor having a sensitive film, a substance adsorption film disposed on the sensitive film and configured to adsorb a smell substance to be detected, and an electrode configured to apply a reference voltage to the substance adsorption film. The substance adsorption film is in a state of releasing a proton in response to absorbing the smell substance.
