| dc.description.abstract |
We study vacuum deposition of molecular MoO3 as an acceptor surface transfer dopant for topological insulator Bi2Se3. We perform high-resolution photoelectron spectroscopy on in-situ cleaved Bi2Se3 single crystals and in-situ transport measurements on Bi2Se3 films grown by molecular beam epitaxy. MoO3 is an efficient acceptor, lowering the surface Fermi energy to within -100 meV of the Dirac point, in the topological regime. A 100 nm MoO3 film provides an air-stable doping and passivation layer. | |
