Distribution of the number of atoms evaporated on efficient pulses in HV mode (left) and LA mode (right).
Mass spectra related to the analysis of the oxide in HV-APT (top) and LA-APT (bottom). Please note the mass resolution improvement by the use of laser pulses.
(a) 3D image of the oxidized iron (in black: Fe, in red: molecular ). (b) Diffraction pattern obtained by Fourier transform. The spots correspond to (220) planes. (c) Filtered 3D images of the Fe atoms by inverse FT on the (220) diffraction spots. The filter threshold is progressively increased from left to right to refine the atomic planes structure.
Distributions of distances between atoms evaporated on a same pulse under HV pulsing and laser pulsing.
