Chemical bonds in ion implanted structures
Tóm tắt
The physical processes of ion implantation are discussed. The chemical bonds between implanted and host atoms depend on the location of the implanted atom in the lattice. The experimental methods used for the investigation of the bonding structure are shortly revlewed. The Mössbauer spectroscopy had proved a powerful method for determining the bonding structures of the implanted atoms. The discussion is limited to57Fe implanted atoms in various hosts and the systematics of the isomer shift is discussed. The analysis showed that the bonding between these atoms results in electron transfer of the bonding s and d electrons. The “anomalous” Mössbauer spectra measured in Bi and Pb lattices are discussed.
