HIGHLIGHTS_______________________________________________________________________________________________
In this work, we have discovered that it is possible to grow self-organized periodically spaced thin ribbons of semi-insulating stripes on the bare Si(100) surface. The epitaxial growth of these structures is obtained by the evaporation of CaF2 molecules on the silicon surface at the transition between the VW and SK modes. They are investigated via scanning tunneling techniques at low temperature (9K). In particular, the obtained thin ribbons exhibit a resonant state at the central part of the ribbons revealling an electronic confinement at a resonnant energy 2eV.
