The Interplay of Topological Surface and Bulk Electronic States in Bi2Se3

In this Letter we present scanning tunneling microscopy density-of-states measurements and electronic structure calculations of the topological insulator Bi2Se3. The measurements show significant background states in addition to the expected Dirac cone. Density functional calculations using a slab m...
