fabrication-the act of making something (a product) from raw materials; the synthesis and fabrication of single crystals; an improvement in the manufacture of explosives; manufacturing is vital to Great Britain.
Two views of the Auger process. (a) illustrates sequentially the steps involved in Auger deexcitation. An incident electron (or photon) creates a core hole in the 1s level. An electron from the 2s level fills in the 1s hole and the transition energy is imparted to a 2p electron which is emitted.The final atomic state thus has two holes, one in the 2s orbital and the other in the 2p orbital.n electron from the 2s level fills in the 1s hole and the transition energy is imparted to a 2p electron which is emitted. The final atomic state thus has two holes, one in the 2s orbital and the other in the 2p orbital.
Auger Electrons. 1. Ionization: A hole in an inner shell (here: K shell) is generated by an incident high-energy electron that loses the corresponding energy E transferred to the ejected electron.* 2.Auger-electron emission: The hole in the K shell is filled by an electron from an outer shell (here: L2).The superfluous energy is transferred to another electron which is subsequently ejected (here: from the L3 level) as Auger electron.ince Auger electrons have an energy in the range of some 100 eV to a few KeV, they are strongly absorbed by the specimen. Consequently, only Auger electron from the surface can be measured, making Auger spectroscopy a surface method. * Energy losses of the incident electrons are measured by EELS.
