The use of HCl during growth of nanowires presents new possibilities for controlling the growth dynamics and resulting nanowire properties. In this paper, we investigate the effects of in situ HCl on the growth of Au-seeded GaAs nanowires in a growth regime where both wurtzite and zinc blende crystal structures are possible to achieve. We find that HCl changes the crystal structure of the nanowires from pure wurtzite to defect-free zinc blende. By comparing the growth of wurtzite-zinc blende… CONTINUE READING
