Description: This image shows highly dense vertical arrays of nanowires made from silicon and titanium oxide. Berkeley Lab scientists prepared these arrays of nanowires consisting of a silicon core coated with a protective shell of titanium oxide, which show promise for the effiecient production of hydrogen through solar water splitting. When these nanowire arrays were grown to heights of 20 microns, their photocurrent was more than doubled compared to planar wafers of silicon and titanium oxide.
