SEM tilted views of nanowire InAs NW arrays grown from EBLprepatterned substrates. The NWs have same diameters but different inter-wire distances: (a) 0.5 µm, (b) 0.75 µm and (c) 1 µm. The nanowires were grown from Au catalysts realized by electron beam lithography. Scale bar is 1 µm in each panel. (Reprinted with permission of Ref. [104]).
