Abstract

A semiconductor light-emitting element of a metal/organic film/semiconductor junction structure has a semiconductor layer, and an organic Langmuir-Blodgett thin film formed on the semiconductor layer. The thin film includes an electron donative organic monomolecular compound whose longest absorption peak wavelength in an electron transition spectrum falls within a range of 300 nm to 600 nm. A layer of metallic material is formed on the thin film.
