NANOSENSORS™ is a proud sponsor of the 2019 Asia-Pacific Workshop on Piezoresponse Force Microscopy ( PFM) and Nanoscale Electromechanics of Functional Materials and Electrochemical Systems (Asia-Pacific PFM 2019), which will be held in Seoul, Republic of Korea, from August 11 to 14, 2019.
We wish all those members of the #AFMcommunity who are participating this week a successful workshop.
In the NANOSENSORS blog you will regularly find references to articles mentioning the use of our AFM probes for Piezoresponse Force Microscopy. You’re welcome to have a look at: https://www.nanosensors.com/blog/tag/pfm/
Abstract: Here, we report the observation of ferroelectric and ferroelastic nanodomains in (110)-oriented BiFeO3 (BFO) thin films epitaxially grown on low symmetric (100) NdGaO3 (NGO) substrate. We observed long range ordering of ferroelectric 109° stripe nanodomains separated by periodic vertical domain walls in as-grown 130 nm thick BFO films. The effect of La 0.67 Sr0.33 CoO3 (LSCO) conducting interlayer on domain configurations in BFO/NGO film was also observed with relatively short range-ordering of stripe domains due to the modified electrostatic boundary conditions in BFO/LSCO/NGO film. Additional studies on B-site doping of Nb ions in BFO films showed change in the domain structures due to doping induced change in lattice anisotropy while maintaining the stripe domain morphology with 109° domain wall. This long-range array of ferroelectric and ferroelastic domains can be useful for optoelectronic devices and ferroelastic templates for strain coupled artificial magnetoelectric heterostructures.
