Possible experimental realization of a basic Z2 topological semimetal in GaGeTe

Possible experimental realization of a basic Z2 topological semimetal in GaGeTe

We report experimental and theoretical evidence that GaGeTe is a basic Z2 topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well as surface state electrons. This electronic situation is qualitatively similar to the classic 3D topological insulator Bi2S...
