Owing to a long term development for reducing the sizes of devices, the preparation of ferroelectric materials and devices are entering nanometer-scale regime. Accordingly, to evaluate the ferroelectricity, there is a need to investigate the polarization charge at the nanoscale. Nonetheless, it has been generally accepted that the detection of polarization charges using a conventional conductive atomic force microscopy (CAFM) without a top electrode is not feasible because the nanometer-scale r","authors_text":"Daehee Seol, Dongkyu Lee, Hee Han, Ho Nyung Lee, Ionela Vrejoiu, Marin Alexe, Owoong Kwon, Sergei V.
