▎ 摘　　要

NOVELTY - The method involves passivating a unit or all of a surface of a charge channel layer by an amorphous hydrocarbon thin film. The thin film is directly grown on the surface of the channel layer or is passivated by transferring the thin film to the surface. A passivation layer is made of the thin-film. The channel layer is selected from silicon, metal oxide semiconductor, organic semiconductor and graphene. A dielectric constant of the film is 10 or more. An electrode is a semiconductor electrode, metal electrode, transparent electrode or a flexible electrode. USE - Method for improving charge mobility of charge channel layer. ADVANTAGE - The charge mobility is remarkably increased by simply passivating the charge channel layer with an amorphous hydrocarbon thin film that can be grown in a simple process using inexpensive raw materials. DESCRIPTION OF DRAWING(S) - The drawing shows a graph showing electrical characteristics of a field-effect transistor including a transferred amorphous hydrocarbon thin film.
