Title:
SEMICONDUCTOR MATERIAL AND LAMINATED SEMICONDUCTOR MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/203846
Kind Code:
A1
Abstract:
[Problem] To provide a semiconductor material and a laminated semiconductor material, each of which is earth-conscious and is less harmful to living organisms. [Solution] The present invention comprises fibers each containing, as a main component, a fiber derived from at least any one of a wood material, a plant fiber (pulp), an animal, an alga, a microorganism and a product produced by a microorganism, and has N-type negative resistance. It is preferred that the fibers comprise bundles of cellulose nanofibers (CNFs) and the width of each of the bundles is 30 to 50 nm. It is also preferred that the fibers comprise fibers in which a plurality of hydroxyl groups and a plurality of carbonyl groups are bound to cellulose.
