      abstract     = {The Te-covered Si(111) surface has received recent interest
                      as a template for the epitaxy of van der Waals
                      (vdW)materials, e.g. Bi2Te3. Here, we report the formation
                      of a Te buffer layer on Si(111)–(7×7) by
                      low-energyelectron diffraction (LEED) and scanning tunneling
                      microscopy (STM). While deposition of several monolayer(ML)
                      of Te on the Si(111)–(7×7) surface at room temperature
                      results in an amorphous Te layer, increasing thesubstrate
                      temperature to 770 K results in a weak (7×7) electron
                      diffraction pattern. Scanning tunneling microscopyof this
                      surface shows remaining corner holes from the
                      Si(111)–(7×7) surface reconstruction andclusters in the
                      faulted and unfaulted halves of the (7×7) unit cells.
                      Increasing the substrate temperature furtherto 920 K leads
                      to a Te/Si(111)–(2 3 × 2 3 )R30° surface reconstruction.
                      We find that this surface configurationhas an atomically
                      flat structure with threefold symmetry.},
