(1-x)KNbO3-xKMgF3 was synthesized using a sealed silica tube with an oxygen generator (KNMOF-O2) or a high-pressure and high-temperature apparatus (KNMOF-hp). The variations in phase transition temperature and dielectric properties were investigat...
Unlike X-ray diffraction or Raman techniques, which suffer from low spatial resolution, transmission electron microscopy can be used to obtain strain maps of nanoscaled materials and devices. Convergent-beam electron diffraction (CBED) and nanobea...

Perovskite oxides hosting ferroelectricity are particularly important materials for modern technologies. The ferroelectric transition in the well-known oxides BaTiO3 and PbTiO3 is realized by softening of a vibration mode in the cubic perovskite s...
Gallium oxynitride (GaON) nanoparticles were synthesized through three steps
(i) hydrothermal treatment of an aqueous solution containing Ga(NO3)3, hexamethylenetetramine (HMT), and acetylene black, (ii) calcination, and (iii) nitridation. The pr...
