We report on growth of GaAs nanowires on Si(111) substrates using Ga droplets by metal-organic chemical vapour deposition (MOCVD). Appropriate growth conditions to achieve stabilization of small Ga droplets as well as Ga-assisted VLS growth of GaAs nanowires were found. This work facilitates comparative studies of crystalline quality and nanowire surfaces as a function of the droplet (catalyst) material.
