Quantized one-dimensional edge channels with strong spin-orbit coupling in 3D topological insulators

Christoph Kastl, Paul Seifert, Xiaoyue He +3

A strong coupling between the electron spin and its motion is one of the prerequisites of spin-based data storage and electronics. A major obstacle is to find spin-orbit coupled ma…

Chemical Potential Fluctuations in Topological Insulator (Bi $_{0.5}$ Sb $_{0.5}$ ) $_{2}$ Te $_{3}$ Films Visualized by Photocurrent Spectroscopy

Christoph Kastl, Paul Seifert, Xiaoyue He +3

We investigate the photocurrent properties of the topological insulator (Bi $_{0.5}$ Sb $_{0.5}$ ) $_{2}$ Te $_{3}$ on SrTiO $_{3}$ -substrates. We find reproducible, submicron photocurrent patte…

Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity

Christoph Kastl, Christoph Karnetzky, Helmut Karl +1

In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insul…
