摘要: Crystal growth performed in situ facilitates interconnection of prefabricated nano-structures. The nano-structures are immersed in a growth solution having a controllable saturation condition. Changing the saturation condition of the solution modifies a size of the immersed nanowires. The solution includes a solute of a nano-structure precursor material. The saturation condition is changed to one or both etch material from a surface of the nano-structures and initiate crystal growth on the nano-structure surface. A nano-structure interconnection system includes the growth solution and equipment to deposit the prefabricated nano-structures on a substrate. An interconnected structure includes a plurality of nano-structures disposed on a substrate in a cluster and a liquid phase-grown crystal lattice on surfaces of the nano-structures to form physical interconnections between the plurality. An ink formulation includes the plurality of nano-structures suspended in the growth solution.
