Room Temperature Ferroelectric Ferromagnet in 1D Tetrahedral Chain Network
Kyeong Tae Kang, Chang Jae Roh, Jinyoung Lim +17
Ferroelectricity occurs in crystals with broken spatial inversion symmetry. In conventional perovskite oxides, concerted ionic displacements within a three-dimensional network of t…
Ferroelectric polarization rotation in order-disorder-type LiNbO3 thin films
Tae Sup Yoo, Sang A Lee, Changjae Roh +16
The direction of ferroelectric polarization is prescribed by the symmetry of the crystal structure. Therefore, rotation of the polarization direction is largely limited, despite th…
Direct Probing of Polarization Charges at the Nanoscale
Owoong Kwon, Daehee Seol, Dongkyu Lee +8
Ferroelectric materials possess spontaneous polarization that can be used for multiple applications. Owing to a long term development for reducing the sizes of devices, the prepara…
Ex-situ atomic force microscopy on the growth mode of SrRuO3 epitaxial thin film
Bora Kim, Sang A Lee, Daehee Seol +2
The functional properties of devices based on perovskite oxides depend strongly on the growth modes that dramatically affect surface morphology and microstructure of the hetero-str…
Non-piezoelectric effects in piezoresponse force microscopy
Daehee Seol, Bora Kim, Yunseok Kim
Piezoresponse force microscopy (PFM) has been used extensively for exploring nanoscale ferro/piezoelectric phenomena over the past two decades. The imaging mechanism of PFM is base…
