摘要: A method of forming a micro-structure (100, 100′, 100″, 100′″) involves forming a multi-layered structure (10) including i) an oxidizable material layer (14) on a substrate (12) and ii) another oxidizable material layer (16) on the oxidizable material layer (14). The oxidizable material layer (14) is formed of an oxidizable material having an expansion coefficient, during oxidation, that is more than 1. The method further involves forming a template (16′), including a plurality of pores (18), from the other oxidizable material layer (16), and growing a nano-pillar (20) inside each pore (18). The nano-pillar (18) has a predefined length (L) that terminates at an end (21). A portion of the template (16′) is selectively removed to form a substantially even plane (23) that is oriented in a position opposed to the substrate (12). A material is deposited on at least a portion of the plane (23) to form a film layer (22, 22′) thereon, and the remaining portion of the template (16′) is selectively removed to expose the nano-pillars (20).

摘要: Methodologies associated with fabricating aligned nanowire lattices are described. One exemplary method embodiment includes providing a twist wafer bonded thin single crystal semiconductor film and a bulk single crystal substrate of the same material. Periodic non-uniform elastic strains present on the surface of the film control the positions where nanocrystals will form on the film. The strains may be removed via annealing and alloying after the formation of nanocrystal arrays.
