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.
yes i used gold layer as seed to start nano structure growth. thanks for comments.
It depends on how would you use the nano structure. If you use it as thin film structure then you can define for it average performance parameters such as average carrier concentration and average mobility.
Other wise these quantities depend on the orientation of the nano wires.
Nano wires are normally used to as one dimensional conductor along the wire.
Best wishes
