Lss theory ion implantation
WebBei der Ionenimplantation spielt die Reichweite der Ionen eine entscheidende Rolle. Eine wichtige Theorie zur Beschreibung der Reichweite von Ionen in amorphen Festkörpern wurde 1963 von Jens Lindhard, Morten Scharff und Hans E. Schiøtt aufgestellt, [1] allgemein als LSS-Theorie bekannt.

[ 14] studied RT N ion implantation (implantation energy = 35 keV, nominal fluence = 5.0 × 10 at/cm) on 3162 steel alloy. The authors observed a 45% increase in hardness after nitrogen implantation and a 17% drop in the friction coefficient.
WebHere, we further developed a quasi crystal LSS (QCLSS) theory that empirically expresses the phenomena associated with crystalline materials such as channeling. We applied the QCLSS theory to ion implantation profiles in Si 1 xGe x substrates and improved it through a comparison with experimental secondary ion mass spectroscopy (SIMS) data. 2. Web1 aug. 1990 · The implantations were carried out at room temperature with an Baton Nova 10-160 ion implantation system, which allows a parallel scanning of the ion beam on the target; the beam divergence was calculated to be less than 2by taking into account the dimensions of the aperture at the exit of the magnet, the length of the beam line and the …
