Abstract: Topological insulators are materials that are electrically insulating in the bulk but can conduct electricity due to topologically protected electronic edge or surface states. Since 2013, the German Research Foundation (DFG) has been supporting the Priority Program “Topological Insulators: Materials – Fundamental Properties – Devices” (SPP 1666). The program has three areas of activity: (i) Understanding and improvement of existing topological insulator materials, regarding the size of the band gap and intrinsic doping levels, to enable room temperature applications, (ii) explore the fundamental properties necessary for the development of device structures, and (iii) discover new materials to overcome deficits of current materials and explore new properties.A considerable number of collaborative works resulted from the activities of the SPP members and the scientific subject as a whole has gained momentum with many initiatives worldwide. In 2016 the Nobel Prize in Physics was awarded to D. J. Thouless, F. D. M. Haldane and J. M. Kosterlitz “for theoretical discoveries of topological phase transitions and topological phases of matter”. This led to a further increase of the awareness for this research field and reflected the fact that topology has nowadays entered and changed our perception of the solid state.The present issue exemplifies and summarizes contributions from the priority program. We have 20 articles, 9 of which are Feature Articles and 11 are Original Papers. The three areas of activity are reflected in the present issue.
