About

The scientific goal of the project "Topological order of electrons in solids: New materials, Phenomena & application Concepts" (UKRATOP) is to design new high-quality materials with exceptional surface and edge conditions resulting from their topological nature. The topological stability of the exotic physical properties of these materials can be of tremendous interest to the next generation of information technology.
UKRATOP is funded by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF) under reference 01DK18002.

Offers

The 2020 call for Scholarships for Master Students will soon be announced.
