Laser Annealing of Ion Implanted Silicon
… and an Ar laser. We use SEM to investigate the electron channelling pattern to study the quality of crystalline regrowth. For BF(,2)('+) implanted silicon, the boron and fluorine atomic profiles are measured by secondary ion mass spectrometry (SIMS) on as-implanted samples as well as laser …

Dynamical models for novel diffraction techniques in SEM
The scanning electron microscope is a powerful nanocharacterisation tool for a variety of materials including semiconductors and metals. Less known for its diffraction abilities than its transmission counterpart, scanning electron microscopy (SEM)can be used in a number of diffraction modalities to …

Development of Multi-Microscopy Techniques for the Characterisation of Nitride Semiconductors
… to understand how particular defects impact the electronic and optical properties. The direct correlation of measurements on the same nanoscale feature between different microscopy techniques can allow a deeper understanding of the interplay between the structural, optical and electronic …

Influence of composition and thermomechanical processing on microstructure evolution in AISI 430 ferritic stainless steel(FSS)
… and 61% for the laboratory heats were studied. Electron channelling contrast (ECC) obtained in scanning electron microscopy was used to follow the evolution of microstructure. Limited micro texture measurements were made using electron backscattered techniques. It was found that a low finish …

A study of millerite from Cu-Ni-PGE footwall veins, Sudbury, ON: crystal-chemistry, morphology, & geological implications
Millerite (-NiS) is a common accessory mineral in magmatic Cu-Ni-PGE deposits, such as those occurring in Sudbury, Ontario, Canada. In such localities, millerite develops as platy crystals, often forming large, cleavable masses. This is in stark contrast to the more widespread occurrence of …
