INFLUENCE OF CATION SUBSTITUTION ON THE ION MIGRATION IN SCHEELITE-TYPE STRUCTURE

Volodymyr Shevchuk, Ihor Kayun

Abstract


A stereo-atomic crystals structure analysis was applied to AMO4 (A=Ba, Ca, Cd, Pb, Sr; M=W, Mo) and solid solutions based on these compounds. The program package TOPOS was used for the calculation. 3D migration paths and migration channels for the W or Mo ions in AMO4 with scheelite-type structure were considered.

Key words: TOPOS, Electro-migration, probable W/Mo migration, migration channel, AMO4 (A=Ba, Ca, Cd, Pb, Sr; M=W, Mo), scheelite.
