The Standard Auger Electron Spectra in The AIST DIO-DB(111); Ge(111)

Abstract

  This paper is a brief review of our final absolute Auger electron spectroscopy which was presented in the work shop on “Electron Transport Parameters Applied in Surface Analysis” (Lake Balaton, Hungary, Sept. 14-17, 2008) as a poster and new data of Ge(111). Some modifications and corrections are made from the poster. This work has been continued in these 21 years and only the significant change was the transmission of the meshes in the analyzer (cylindrical mirror analyzer); effective transmission being 0.22sr and 0.199(9)sr for 42.3 ±6 degrees of emission cone for the data before and after 2008, respectively. This change was due to the over-coating of soot on the former aquadag coating on the gold plated tungsten meshes to stabilize the work function and to reduce the scattered electrons and secondary electrons at the mesh. These Auger electron spectra can now be available on the web; http://www.sasj/COMPRO and http://riodb.ibase.aist.go.jp/DB111/welcome.html.
