Secondary electron emission model for photo-emission from metals in the vacuum ultraviolet
文献摘要：
This study investigates two secondary electron emission(SEE)models for photoelectric energy distribu-tion curves f(Eph,hγ),B,Emean,absolute quantum effi-ciency(AQE),and the mean escape depth of photo-emitted electrons λ of metals.The proposed models are developed from the density of states and the theories of photo-emis-sion in the vacuum ultraviolet and SEE,where B is the mean probability that an internal photo-emitted electron escapes into vacuum upon reaching the emission surface of the metal,and Emean is the mean energy of photo-emitted electrons measured from vacuum.The formulas for f(Eph,hy),B,λ,Emean,and AQE that were obtained were shown to be correct for the cases of Au at hγ=8.1-11.6 eV,Ni at hγ=9.2-11.6 eV,and Cu at hγ=7.7-11.6 eV.The pho-toelectric cross sections(PCS)calculated here are ana-lyzed,and it was confirmed that the calculated PCS of the electrons in the conduction band of Au at hγ=8.1-11.6 eV,Ni at hγ=9.2-11.6 eV,and Cu at hγ=7.7-11.6 eV are correct.
