Precursor flow rate manipulation for the controlled fabrication of twin-free GaAs nanowires on silicon substrates.
Vertically oriented GaAs nanowires (NWs) are grown on Si(111) substrates using metal-organic chemical vapor deposition. Controlled epitaxial growth along the <111> direction is demonstrated following the deposition of thin GaAs buffer layers and the elimination of structural defects, s...
