Title: Observation of cyclotron resonance and electron-phonon coupling in surface states of the bulk-insulating topological insulator Cu0.02Bi2Se3

Standard time-domain THz spectroscopy (TDTS) in a transmission geometry was performed with a custom home-built THz spectrometer. In this technique an approximately single-cycle picosecond pulse of light is transmitted through the sample and the substrate. The complex transmission is obtained from Fourier transforming the time-domain sample pulse and ratioing it to a Fourier transformed substrate pulse.
