(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...
