Abstract: The present invention relates to a method of fabricating a black phosphorus thin film and a black phosphorus thin film thereof and, more particularly, to a method of fabricating a black phosphorus ultrathin film by forming the black phosphorous ultrathin film in a chamber by active oxygen and removing accompanying black phosphorus oxide film water. The black phosphorus ultrathin film has a surface that does not substantially have defects and is uniform in a large area, and has a surface roughness property of 1 nm or less, to represent a high application property to an optoelectronic device and a field effect transistor.
