“…As a result, part of the scattering channels at the Fermi energy level is absent, serving as a source for unique transport properties, including negative refraction between different surfaces [41]. In reality, the electronic transport signatures will depend on the material details and their specific termination, both of which affect the Fermi arcs' orientation, dispersion, and length [12][13][14][15][16][17][42][43][44]. Notably, however, stateof-the-art fabrication techniques allow for controlled surface shaping on the level of a single layer [16,18,45,46], making it possible to explore the broad breadth of surface transport phenomena.…”
