Investigation of new semiconductor materials for wide band-gap devices
… were wavelength dispersive X-ray spectroscopy (WDX) and cathodoluminescence (CL) with other electron microscopy and spectroscopic techniques used to assist in the characterisation of the semiconductor materials. Compositional measurements were performed to determine bulk alloying levels within …

Solid solubility of silver in the superconducting YBa₂Cu₃O compound
… (EDX), wavelength dispersive X-ray spectroscopy (WDX), and secondary ion mass spectrometry (SIMS). The lattice parameters were precisely determined by a rigorous X-ray diffraction method and by using a USGS computer program which uses an iterative least square solution to calculate the lattice …

The effect of Zr and ZrB2 additions to NdFeB alloys
… in the sintered magnets. Both SEM (equipped with WDX) and TEM (equipped with EDX) have been employed to investigate ZrB2 needles in Nd12.68Fe77.91-80.91B6.41-8.41Zr0-1 (at%) alloys. It is found that suppression of free α-Fe dendrites in both Zr-containing NdFeB alloys resulted from different …
