| contents | The checkerboard lattice has been proposed to host topological flat bands as a result of destructive interference among its various electronic hopping terms. However, it has proven challenging to realize experimentally due to the difficulty of isolating this structure from any significant out-of-plane bonding while maintaining structural integrity. Here, single crystals of Zr2CuSb3, a potential candidate for the checkerboard lattice, were synthesized using the solution (self-flux) method, and their structure was confirmed via X-ray diffraction. Electrical transport measurements indicate metallic behavior with electron-dominated carriers. Angle-resolved photoemission spectroscopy reveals multiple electron pockets and significant kz broadening due to its large c-axis and low dispersion features in k z. Density functional theory calculations further disentangle the contributions from each high-symmetry plane, providing a comprehensive characterization of electronic behavior. |
