Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

Heusler compounds, initially discovered by Fritz Heusler more than a century ago, have
grown into a family of more than 1,000 compounds, synthesized from combinations of more …

A variety of monolayer crystals have been proposed to be two-dimensional topological
insulators exhibiting the quantum spin Hall effect (QSHE), possibly even at high …

These lecture notes provide an introduction to some of the main concepts of topological
insulators, a branch of solid state physics that is developing at a fast pace. They are based …

The Chern insulator displays a quantized Hall effect without Landau levels. Theoretically,
this state can be realized by engineering complex next-nearest-neighbour hopping in a …

Topological phases with insulating bulk and gapless surface or edge modes have attracted
intensive attention because of their fundamental physics implications and potential …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

We have engineered electron-hole bilayers of inverted InAs/GaSb quantum wells, using
dilute silicon impurity doping to suppress residual bulk conductance. We have observed …

Topological insulators are electronic materials that have a bulk band gap like an ordinary
insulator but have protected conducting states on their edge or surface. These states are …

It has recently been shown that in every spatial dimension there exist precisely five distinct
classes of topological insulators or superconductors. Within a given class, the different …
