1. A method for patterned deposition of material on nanostructures, the method comprising:
providing a growth substrate having at least one shadow structure, wherein at least a part of said at least one shadow structure is vertically offset from the growth surface on the growth substrate,
growing at least one nanostructure on the growth surface of the growth substrate, or from the growth surface of the growth substrate, in the vicinity of said at least one shadow structure and such that at least initially the growth plane of the at least one nanostructure is vertically offset from at least a part of the at least one shadow structure, wherein an initial growth of the at least one nanostructure occurs after providing the shadow structure; and
depositing at least a first layer of material on at least a part of the at least one nanostructure by means of at least a first deposition source,
wherein the at least first deposition source, the at least one shadow structure and the at least one nanostructure are arranged such that, during deposition of said at least first layer, at least a part the at least one shadow structure forms at least one shadow mask on the at least one nanostructure relative to the deposition source.
