In this work, oxide conduction in γ-Bi 2VO 5.5 is modeled based on bond valence sum (BVS) method. In γ-Bi 2VO 5.5, there are oxide vacancies at the equatorial position in the perovskite-like layers. These vacancies can facilitate oxide movement. The γ-Bi 2VO 5.5 model was built in a primitive structure with the entire V coordination in one layer are tetrahedron and entire V coordination in the next layer are octahedron. Oxygen movement, based on BVS result, mainly occurs in equatorial site i.e. on [140] direction. The minimum achieved BVS value was 1.320, which is considered as a site that has large cavity and facilitates oxygen hopping. © 2011 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bond-valence sum,BVS,Equatorial positions,Equatorial sites,oxygen conduction[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]γ-Bi 2VO 5.5,BVS,oxygen conduction[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICICI-BME.2011.6108652[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
