abstract = {We investigated the growth of the topological insulator
Bi2Te3 on Si(1 1 1) substrates by means of molecular-beam
epitaxy (MBE). The substrate temperature as well as the Bi
and Te beam-equivalent pressure (BEP) was varied in a large
range. The structure and morphology of the layers were
studied using X-ray diffraction (XRD), X-ray reflectivity
(XRR) and atomic force microscopy (AFM). The layer-by-layer
growth mode with quintuple layer (QL) as an unit is
accomplished on large plateaus if the MBE growth takes place
in a Te overpressure. At carefully optimized MBE growth
parameters, we obtained atomically smooth, single-crystal
Bi2Te3 with large area single QL covering about $75\%$ of
the layer surface. Angular-resolved photoelectron
spectroscopy reveals a linear energy dispersion of charge
carriers at the surface, evidencing topologically insulating
properties of the Bi2Te3 epilayers. (C) 2011 Elsevier B.V.
