Defects and dopants create conduction in thermoelectric applications. However, such defects may degrade the performance as a topological insulator (TI). Magnetic impurities such as iron open a band gap at the Dirac point on the surface. Since magnetically-doped TIs are important in technological applications, a good understanding of their properties is needed. In this article, 77Se nuclear magnetic resonance (NMR) spectroscopy has been used to investigate Fe-doped Bi2Se3.
