  bibo_abstract:
  - Linear phase‐contrast scanning transmission electron microscopy (STEM) techniques
    compatible with high‐throughput 4D‐STEM acquisition are widely used to enhance
    phase contrast in weakly scattering and beam‐sensitive materials. In these modalities,
    contrast transfer is often suppressed at low spatial frequencies, resulting in
    a characteristic contrast gap that limits contrast. Approaches that retain low‐frequency
    phase contrast exist but typically require substantially increased experimental
    complexity, restricting routine use. Dark‐field STEM imaging captures this missing
    low‐frequency information through electrons scattered outside the bright‐field
    disk, but discards a large fraction of the scattered signal and is therefore dose‐inefficient.
    Fused Full‐field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that
    overcomes these limitations by combining ptychographic phase reconstruction with
    tilt‐corrected dark‐field imaging within a single acquisition. Bright‐field data
    are used to estimate probe aberrations and reconstruct a high‐resolution phase
    image, while dark‐field data provide complementary low‐frequency contrast. The
    two channels are fused in Fourier space using Wiener‐band weighting based on the
    spectral signal‐to‐noise ratio, yielding transfer‐gap‐free images with high contrast.
    FF‐STEM preserves the upsampling and depth‐sectioning capabilities of ptychography,
    adds robust low‐frequency contrast characteristic of dark‐field imaging, and enables
    dose‐efficient, near–real‐time reconstruction.@eng
