Imaging Dirac-mass disorder from magnetic dopant atoms in the ferromagnetic topological insulator Cr <sub>x</sub> (Bi <sub>0.1</sub> Sb <sub>0.9</sub> ) <sub>2-x</sub> Te <sub>3</sub>
To achieve and utilize the most exotic electronic phenomena predicted for the surface states of 3D topological insulators (TI),it is necessary to open a "Dirac-mass gap" in their spectrum by breaking time-reversal symmetry. Use of magnetic dopant atoms to generate a ferromagnetic state is the most widely used approach. But …
