    • Diffuse reflectance spectroscopy measurements of β -K2 Bi8 Se13 at room temperature suggested an apparent band gap of □0.59 eV (Ref.). The key difference between the optical and tunneling measurements of the band gap is that optical measurements are sensitive to wave vector k and optical matrix element connecting the valence and conduction band states. In contrast, the tunneling measurements are sensitive to the matrix element between the states of the system and the tip. This difference may be the reason for observed difference in the values of the band gap seen in tunneling and reflectance spectroscopy measurement.
