Realization of a vertical topological p-n junction in epitaxial heterostructures
Markus Eschbach, Ewa Mlynczak, Jens Kellner +17
3D topological insulators are a new state of quantum matter which exhibits both a bulk band structure with an insulating energy gap as well as metallic spin-polarized Dirac fermion…
Sub-nm wide electron channels protected by topology
Christian Pauly, Bertold Rasche, Klaus Koepernik +11
Helical locking of spin and momentum and prohibited backscattering are the key properties of topologically protected states. They are expected to enable novel types of information…
Evidence for topological band inversion of the phase change material Ge2Sb2Te5
Christian Pauly, Marcus Liebmann, Alessandro Giussani +8
We present an angle-resolved photoemission study of a ternary phase change material, namely Ge2Sb2Te5, epitaxially grown on Si(111) in the metastable cubic phase. The observed uppe…
