Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3
Advanced Functional Materials, EarlyView.Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...
