Spatial Eigenanalysis of 2D Deformation Energies

Abstract We present the first closed‐form, per‐element eigensystems for 2D deformation energies in the primary domain of spatial coordinates. Previous analyses have only been able to find such eigensystems in proxy coordinates such as the deformation gradient, but as the spatial...

Impact of oxygen and hydrogen traces on the focused ion beam sputter rate and secondary ion mass spectrometry intensity detection of graphite

Trace amounts of oxygen and hydrogen can strongly influence the formation of negative carbon ions during focused ion beam–secondary ion mass spectrometry (SIMS) analysis of graphite. In this study, the sputtering behavior of graphite and the detection of single and clustered carb...
