      abstract     = {The composition and band gap of the shell that formed
                      during the growth of axial GaAs/GaAs81 Sb 19/ GaAs
                      heterostructure nanowires have been investigated by
                      transmission electron microscopy combined with energy
                      dispersion spectroscopy, scanning tunneling spectroscopy,
                      and density functional theory calculations. On the GaAs 81
                      Sb 19 intermediate segment, the shell is found to be free of
                      Sb (pure GaAs shell) and transparent to the tunneling
                      electrons, despite the (110) biaxial strain that affects its
                      band gap. As a result, a direct measurement of the core band
                      gap allows the quantitative determination of the band offset
                      between the GaAs 81 Sb 19 core and the GaAs shell and
                      identifies it as a type I band alignment.},
