Read how Nanoworld Arrow-EFM AFM probes were used in the paper “Ferroelectric domains and phase transition of sol-gel processed epitaxial Sm-doped BiFeO3 (001) thin films” in which the authors Zhen Zhou, Wie Sun, Zhenyu Liao, Shuai Ning, Jing Zhu and Jing-Feng Li:
- prepared 12% Sm-doped BiFeO3 epitaxial thin films on Nb-doped SrTiO3 (001) substrate via a sol-gel method
- used PFM (piezoresponse force microscopy) to characterize the in-situ ferroelectric domain evolution from room temperature to 200 °C
- illustrated a phase transition from ferroelectric to antiferroelectric phase by SS-PFM and found a significant piezoelectric response at the phase boundary
Their work revealed the origin of the high piezoresponse of Sm-doped BiFeO3 thin films at the morphotropic phase boundary (MPB).*
A PtIr-coated NanoWorld Arrow-EFM cantilever with a nominal spring constant of 2.8 N/m and a typical resonant frequency of 75 kHz was used in all imaging modes mentioned in the article.
