Combining Angle resolved photoelectron spectroscopy (ARPES) and a μ-focused Laser, we have performed scanning ARPES microscopy measurements of the domain population within the nematic phase of FeSe single crystals. We are able to demonstrate a variation of the domain population density on a scale of a few 10 μm while constraining the upper limit of the single domain size to less than 5 μm. This experiment serves as a demonstration of how combining the advantages of high resolution Laser ARPES and an ultimate control over the spatial dimension can improve investigations of materials by reducing the cross contamination of spectral features of different domains.

Here we choose to set the color scale in such a way that within the chosen area of interest of constant orientation, the lowest and highest values would be represented as the brightest green and red respectively.
