  "description": "<p>In this paper the influence of 2s Bloch wave states on high angle annular dark field image contrast is studied<br>\nquantitatively by Bloch wave and multislice simulations. We show that 2s states are excited beyond a critical Z<br>\nvalue and cause a long period oscillation of the electron probe wave function that significantly influences the Z<br>\ncontrast. As a result, we find that the Z contrast for high Z alloys remains thickness dependent up to high sample<br>\nthicknesses and this effect has to be considered for compositional analysis. In the special case of ordered alloys,<br>\nthe impact of 2s excitations on intensity provides a way to quantify long-range order phenomena in alloys with<br>\nknown composition.</p>",
