Downsizing process of Pt/CaySr1−yBi2Ta2O9/(HfO2)x(Al2O3)1−x/Si ferroelectric-gate field-effect transistors (FeFETs) were reviewed. Self-aligned-gate process was applied for developing the FeFETs. We measured memory windows, endurances, and retentio
In this phase, the planes of the superstructure form preferred migration paths10. Preferred horizontal growth of the brownmillerite phase is also observed when oxygen vacancies are formed during the first switching event at positive voltages, as illustrated by the STEM images of Supplementary Fig. ...
This second-order phase transition breaks the in-plane symmetry, and two possible isoenergetic orbital domains can form. The domains consist of CE-type5 zig-zag chains6 oriented along one of two possible crystallographic directions, which give rise to anisotropic optical and electronic properties7,...
With Ca2+ or Zn2+ added to the silicate host, the crystal phase could be transformed between the -form and the β-form of the Sr2SiO4 structure. Under UV excitation at 367nm, all samples exhibit a broad band emission from 420 to 680nm due to the 4f65d1→4f7 transition of Eu2+ ...
Above T f , the ZFC (zero-field-cooled) relaxation follows the stretched exponential form while the FC (field-cooled) relaxation rate can be well described by a power law. These magnetic relaxation phenomena can be attributed to the local interactions between ferromagnetic clusters in La 0.75 ...
