I have synthesized CdZnS semiconductor nano-wires on ITO substrates, is it possible to measure carrier concentration and mobility through Hall Effect HMS-5000 system because it assumes that thin films are uniform while nano-structures are wool like.
Did you use a seed layer before nano structure growth?? If so.. then I think you can determine as you have wished (Using lateral contact). Otherwise, you can make sandwich contact between ITO and top of the nano wires.
