Abstract

A CaFbuffer layer () is formed on a CaF(111) substrate () by an MBE method. Furthermore, a CuCl thin film is grown on the CaFbuffer layer () by the MBE method while irradiating it with an electron beam to form an electro beam irradiation film (). Subsequently, a CuCl thin film is grown by the MBE method without the irradiation of electron beam to form an electron beam non-irradiation film (), thereby thus forming a CuCl thin film (a) including the electron beam irradiation film () and the electron beam non-irradiation film (). Consequently, a CuCl thin film () exhibiting high planarity and crystallinity can be formed.
