                      (X-PEEM) is a well-established methodfor imaging
                      ferroelectric domain structures. Here, we expand the scope
                      of application of X-PEEMand demonstrate its capability for
                      imaging and investigating domain walls in ferroelectrics
                      withhigh spatial resolution. Using ErMnO3 as test system, we
                      show that ferroelectric domain walls canbe visualized based
                      on photo-induced charging effects and local variations in
                      their electronicconductance can be mapped by analyzing the
                      energy distribution of photoelectrons. Our resultsopen the
                      door for non-destructive, contact-free, and element-specific
