Accurate computation of chemical contrast in field ion microscopy
Shalini Bhatt, Shyam Katnagallu, Jörg Neugebauer +1
We present a computational approach to simulate local contrast observed in Field Ion Microscopy (FIM). It is based on density-functional theory utilizing the Tersoff-Hamann approac…
Ab initio vacancy formation energies and kinetics at metal surfaces under high electric field
Shyam Katnagallu, Christoph Freysoldt, Baptiste Gault +1
Recording field ion microscope images under field evaporating conditions and subsequently reconstructing the underlying atomic configuration, called three-dimensional field ion mic…
Construction and analysis of surface phase diagrams to describe segregation and dissolution behavior of Al and Ca in Mg alloys
Jing Yang, K. B. Sravan Kumar, Mira Todorova +1
Segregation and dissolution behavior of Mg alloyed with Ca and Al are studied by performing density functional theory calculations considering an extensive set of surface structure…
