Terahertz Magnetospectroscopy of Cyclotron Resonances from Topological Surface States in Thick Films of Cd${}_x$Hg${}_{1-x}$Te

M. Otteneder, D. Sacré, I. Yahniuk +10

We present studies of the cyclotron resonance (CR) in thick Cd${}_x$Hg${}_{1-x}$Te films with different cadmium concentrations corresponding to inverted and normal band order, as well…
