Abstract
⺠Both elastic and inelastic scattering in STEM are acceleration voltage dependent. ⺠HAADF, EELS and ABF imaging are assessed with a view to optimum imaging. ⺠Lower accelerating voltages improve STEM EELS contrast in very thin crystals. ⺠Higher accelerating voltages give better STEM EELS contrast in thicker crystals. ⺠At fixed resolution, higher accelerating voltage aids ABF imaging of light elements.
