Quantum Hall effect and current distribution in the 3D topological insulator HgTe
S. Hartl, L. Freund, M. Kühn +8
We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain. Des…

Impact ionization induced by terahertz radiation in HgTe quantum wells of critical thickness
S. Hubmann, G. V. Budkin, M. Urban +9
We report on the observation of terahertz (THz) radiation induced band-to-band impact ionization in \HgTe quantum well (QW) structures of critical thickness, which are characterize…
