Space- and time-resolved mapping of ionic dynamic and electroresistive phenomena in lateral devices.
A scanning probe microscopy-based technique for probing local ionic and electronic transport and their dynamic behavior on the 10 ms to 10 s scale is presented. The time-resolved Kelvin probe force microscopy (tr-KPFM) allows mapping of surface potential in both space and time domains, visualizing electronic and ionic charge dynamics and separating underlying processes based on their time respo...
The magnetic characteristics of a nanocrystalline material based on bismuth ferrite Bi2Fe4O9 with 60±3 nm crystallites were studied. obtained demonstrates unusual properties, which are manifested in significant increase the value magnetization comparison data known from other works.
We report the fabrication of novel multiferroic nanostructured bismuth ferrite (BiFeO(3)) fibers using the sol-gel based electrospinning technique. Phase pure BiFeO(3) fibers were prepared by thermally annealing the electrospun BiFeO(3)/polyvinylpyrrolidone composite fibers in air for 1 h at 600 °C. The x-ray diffraction pattern of the fibers (BiFeO(3)) obtained showed that their crystalline st...
