探針がカンチレバー先端より突出し、直上から探針先端を観察可能。NANOSENSORS アドバンスドテック AdvancedTEC™ (ATEC) プローブ

アドバンスドテックシリーズはシャープな三角錐の探針がカンチレバー先端より更に前方へと突き出ているのが特長。

探針を確実に測定領域にポジショニングしたい場合や、探針先端を直接見ながら作業するナノマニピュレーションなどのアプリケーションに最適です。

Happy Swiss National Holiday with Smallest Swiss Cross

Basel University : Smallest Swiss Cross – Made of 20 Single Atoms ( a NANOSENSORS PPP-NCL was used for this image)

20 bromine atoms positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature, creating a Swiss cross with the size of 5.6nm. The structure is stable at room temperature and was achieved by exchanging chlorine with bromine atoms. (Fig: University of Basel, Department of Physics), image made with NANOSENSORS PPP-NCL AFM tip

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.
