"We present an experimental study of the electronic states of the nanolamellar compound ${\mathrm{Ti}}_2\mathrm{SnC}$ by means of angle-resolved photoemission spectroscopy (ARPES). Experiments were performed on macroscopic single crystals, and the observed Fermi surface and band structure were systematically compared with the output of density functional theory calculations. The fine details of the Fermi surface predicted by theory are duly evidenced by the ARPES measurements. The multiply connected Fermi surface (FS) is formed by a combination of quasi-two-dimensional corrugated tubes and quasi-one-dimensional thin plates, centered on high-symmetry axes and points, respectively. The quasi-one-dimensional FS region displays a clear Dirac-like dispersion. An evanescent surface state is observed in addition to the bulk bands."
