Epitaxial BiFeO3 thin films on Si
BiFeO3 was studied as an alternative environmentally clean ferro/piezoelectric material. 200-nm-thick BiFeO3 films were grown on Si substrates with SrTiO3 as a template layer and SrRuO3 as bottom electrode. X-ray and transmission electron...

| description | BiFeO3 was studied as an alternative environmentally clean ferro/piezoelectric material.
200-nm-thick BiFeO3 films were grown on Si substrates with SrTiO3 as a template layer and
SrRuO3 as bottom electrode. X-ray and transmission electron microscopy studies confirmed the epitaxial growth of the films. The spontaneous polarization of the films was ~45μC/cm2.
Retention measurement up to several days showed no decay of polarization. A piezoelectric
coefficient (d33) of ~60 pm/V was observed, which is promising for applications in
micro-electro-mechanical systems and actuators. |
