Query: Electron Transport in InAs-InAlAs Core-Shell Nanowires   Evidence is given for the effectiveness of InAs surface passivation by the
growth of an epitaxial InAlAs shell. The electron mobility is measured as a
function of temperature for both core-shell and unpassivated nanowires, with
the core-shell nanowires showing a monotonic increase in mobility as
temperature is lowered, in contrast to a turnover in mobility seen for the
unpassivated nanowires. We argue that this signifies a reduction in low
temperature ionized impurity scattering for the passivated nanowires, implying
a reduction in surface states.
