DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis
Journal of Applied Crystallography, EarlyView.DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Reliable fatigue design of welded components under multiaxial loading demands local criteria able to capture both the stress gradient at the weld notches and the influence of a complex loading condition including non proportionality of the stress‐strain load history. The Effective Critical Plane (ECP) approach, based on a stress averaging over

In operando imaging of the space‐charge region in a 4H‐SiC MOSCAP using STEM‐EBIC
Journal of Microscopy, EarlyView.Abstract In situ biasing electron microscopy is the necessary step forward in being able to characterise nanoscale devices and device interfaces. STEM‐EBIC is a new approach that can help fill the missing gaps in creating reproducible methodologies for in situ biasing TEM.

Study of Ion Induced Damage in 4H-SiC
Materials Science Forum, 2005 The damage produced by 2 MeV protons on a 4H-SiC Schottky diode has been investigated by monitoring the charge collection efficiency as the function of the ion fluence. A new algorithm based on the Shockley-Ramo-Gunn theorem has been developed to interpret the experimental results. The fitting procedure provides a parameter which is proportional to the
