Channeling in Zinc-Blende Lattices: Energy-Loss Studies for Hydrogen and Helium Ions in InAs, GaSb, AlSb, and InSb

The energy losses of ions channeled in InAs, GaSb, AlSb, and InSb were investigated. The average number of electrons/atom participating in the stopping of channeled particles is about the same for GaSb and InAs. The minimum energy losses along the [111] and [$\overline{1}\overline{1}\overline{1}$] directions were investigated for GaSb and AlSb and were found to be independent of this asymmetry. The lattice parameter has a stronger influence on the minimum energy losses in channeling of zinc-blende compounds than the $A$ or $Z$ of the host-lattice atoms. The $Z$ dependence of incident light ions channeled in a given host lattice is the same as that for normal energy losses. The energy losses of axial channeling were investigated for GaSb and appear to be characterized by the energy losses of the plane having the largest interplanar spacing in the axial intersection.
