Nanoparticles made of “pure” and Ni-“doped” Bi2Se3 prototype topological insulators were successfully prepared using the chemical hot-injection method. In both cases, the reaction is kept for a relatively long period, where samples are taken

Theoretical progress in graphene physics has largely relied on the application of a simple nearest-neighbor tight-binding model capable of predicting many of the electronic properties of this material. However, important features that include electro

Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe quantum well bands with zone-f
