Method for Suppression of Stacking Faults in Wurtzite III−V Nanowires

Abstract
The growth of wurtzite GaAs and InAs nanowires with diameters of a few tens of nanometers with negligible intermixing of zinc blende stacking is reported. The suppression of the number of stacking faults was obtained by a procedure within the vapor−liquid−solid growth, which exploits the theoretical result that nanowires of small diameter (∼10 nm) adopt purely wurtzite structure and are observed to thicken (via lateral growth) once the axial growth exceeds a certain length.
