A method of electrically contacting vertically grown nanowires of uneven heights, a common scenario among as-grown nanowires, is reported here using a chemically synthesized single-crystalline Au microplate as top electrode. The contact is electrically activated and the contact formation is predominantly due to electromigration. With this approach, the electrode could ohmically contact several thousand nanowires at once.
