Revealing atomic-scale vacancy-solute interaction in nickel
Felipe F. Morgado, Shyam Katnagallu, Christoph Freysoldt +7
Imaging individual vacancies in solids and revealing their interactions with solute atoms remains one of the frontiers in microscopy and microanalysis. Here we study a creep-deform…
A model to predict image formation in the three-dimensional field ion microscope
Benjamin Klaes, Rodrigue Larde, Fabien Delaroche +5
This article presents a numerical model dedicated to the simulation of field ion microscopy (FIM). FIM was the first technique to image individual atoms on the surface of a materia…
Imaging individual solute atoms at crystalline imperfections in metals
Shyam Katnagallu, Leigh T. Stephenson, Isabelle Mouton +11
Directly imaging all atoms constituting a material and, maybe more importantly, crystalline defects that dictate materials' properties, remains a formidable challenge. Here, we pro…
Advanced data mining in field ion microscopy
Shyam Katnagallu, Baptiste Gault, Blazej Grabowski +3
Field ion microscopy (FIM) allows to image individual surface atoms by exploiting the effect of an intense electric field. Widespread use of atomic resolution imaging by FIM has be…
