Modeling mass spectrometry profiles in atom probe tomography

摘要: An investigation of Atom Probe machine parameters on spectral resolution suggested that the traditional model for additive errors did not fully explain changes in peak shape due to experimental settings. We propose a new hypothesis explains effects seen spectra and provides additional information about chemical bonding material under examination. Our requires thermal vibration critical momentum photon sufficient energy must coincide at single lattice point provide an evaporation. Using equations derived from this hypothesis, we demonstrate utility approach, which process evaporation using Probe.
