SWITCHING ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a switching element which materializes a bistable characteristic without scattering conductive fine particles in an organic bistable material.

SOLUTION: The switching element has two types of stable resistance value with respect to a voltage applied across electrodes, and a first electrode layer 21a. An organic bistable material layer 30 and a second electrode layer 21b are formed in this order on a substrate as a thin film. The organic bistable material layer 30 contains a functional group of electron-releasing properties and a functional group of electron-accepting properties in one molecule, and the surface roughness Ra of the organic bistable material layer 30 is 1.0 nm or more, and Ra is 70% or less of a film thickness of the organic bistable material layer 30.
