Nanowire thickness alters GaAs band structure


Physics World reports that Researchers from Solid State Physics have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that the spatial confinement along the radius of a nanowire resulted in bending of the band structure of the material.
