    Abstract: Provided is an organic modulation element including an organic modulation layer containing a plurality of organic semiconductor molecules, a first electrode, and a second electrode. Each of the plurality of organic semiconductor molecules is a molecule in which an excited state enabling reverse intersystem crossing from a lowest excited triplet state to a lowest excited singlet state is formed due to irradiation with the input light. In each of the plurality of organic semiconductor molecules, an intersystem crossing rate constant from the lowest excited singlet state to the lowest excited triplet state is greater than a reverse intersystem crossing rate constant from the lowest excited triplet state to the lowest excited singlet state, and the reverse intersystem crossing rate constant from the lowest excited triplet state to the lowest excited singlet state is greater than a non-radiative deactivation rate constant from the lowest excited triplet state to a ground state.

    Abstract: A method for manufacturing an organic semiconductor element includes a process of forming a first terminal on a main surface of a substrate, a process of forming a first electrode on the main surface, a process of forming an organic semiconductor layer on the first electrode, a process of forming a second electrode on the organic semiconductor layer, a process of forming a sacrificial layer in a predetermined region on the main surface, a process of forming a barrier layer on the main surface by an ALD method to cover the first terminal, the first electrode, the second electrode, the organic semiconductor layer, and the sacrificial layer, and a process of removing the sacrificial layer and a portion of the barrier layer that covers the sacrificial layer. The organic semiconductor layer and the sacrificial layer are apart from each other after the process of forming the barrier layer.
