Photovoltaic Light Funnels Grown by GaAs Nanowire Droplet Dynamics
Abstract
GaAs nanowire (NW) arrays were grown on Si substrates by selective-area molecular beam epitaxy (MBE) using the self-assisted vapor-liquid-solid (VLS) method. In the self-assisted VLS method, the GaAs NW diameter is determined by the size of a Ga droplet at the top of the NW. Absorption of the solar spectrum for photovoltaic devices is optimum with a GaAs NW diameter of 170nm, requiring a Ga droplet during the growth of a similar size. Control …
