Angle-resolved photoemission spectroscopy (ARPES) presents significantsimplications in analyzing strictly two-dimensional (2D) materials, but eventhe most anisotropic physical systems display some residualthree-dimensionality. Here we demonstrate how this third dimension manifestsitself in ARPES spectra of quasi-2D materials by considering the example of thecuprate Bi$_2$Sr$_2$CaCu$_2$O$_{8}$ (Bi2212). The intercell, interlayerhopping, which is responsible for $k_z$-dispersion of the bands, is found toinduce an irreducible broadening to the ARPES lineshapes with a characteristicdependence on the in-plane momentum $k_\parallel$. Our study suggests thatARPES lineshapes can provide a direct spectroscopic window for establishing theexistence of coherent c-axis conductivity in a material via the detection ofthis new broadening mechanism, and bears on the understanding of 2D to 3Dcrossover and pseudogap and stripe physics in novel materials through ARPESexperiments.Comment: 5 pages, 4 figure
