Project

Origin of Room Temperature Ferromagnetism in Thin Films of Undoped d0 Semiconducting Oxides (GA22-21547S)

(by doping Ta and C, or inducing oxygen vacancies on purpose etc.) into the oxide films on the origin of the observed FM, however, there were some evidences showing that oxygen vacancies and/or other defects would...

The role of the stress state and vacancy supersaturation in formation of binary-phase hollow nanospheres (GAP108/10/1781)

Hollow nanospheres can be formed e.g. by oxidation of metallic nanospheres. If the diffusion coefficient of the metallic component in the oxide shell is higher that that of oxygen, the hollow develops as a result of Kirkendall effect. This p...
