Manipulating the Polar mismatch at LaNiO3/SrTiO3 (111) Interface
Mohammad Saghayezhian, Zhen Wang, Hangwen Guo +3
Heteroepitaxial growth of transition-metal oxide films on the open (111) surface of SrTiO3 results in significant restructuring due to the polar mismatch. Monitoring the structural…
Unusual Fe-H bonding associated with oxygen vacancies at the (001) surface of Fe3O4
Fangyang Liu, Chen Chen, Hangwen Guo +6
An unusual Fe-H bonding rather than conventional OH bonding is identified at Fe3O4 (001) surface. This abnormal behavior is associated with the oxygen vacancies which exist on the…
Polar compensation at the surface of SrTiO3 (111)
Mohammad Saghayezhian, Lina Chen, Gaomin Wang +3
We have systematically investigated the annealing effect on the structure and composition of the polar surface of SrTiO3 (111), starting with an ex-situ chemical etch. The relative…
