Patent ID: 7679077

Claim:
A nanodevice comprising: a substrate; at least one first electrode comprising a one-dimensional nanostructure extending from the substrate; at least one functional layer having a desired function, each functional layer contacting and surrounding at least a portion of a corresponding one-dimensional nanostructure, wherein at least one said functional layer comprises at least one of: a semiconductor compound superlattice thin film, a multi-layered semiconductor superlattice structure, a multi-layered structure, a diluted magnetic semiconductor multi-layered superlattice structure, a spin-valve structure, a giant magnetoresistance structure, and a colossal magnetoresistance structure; wherein the multi-layered structure comprises of at least one of: ferromagnetic/nonmagnetic/ferromagnetic, ferromagnetic/antiferromagnetic/ferromagnetic, and ferromagnetic/paramagnetic/ferromagnetic superlattice structures; at least one second electrode of a conductive thin film contacting and surrounding at least one functional layer; and at least one insulating layer positioned between the substrate and a corresponding second electrode, each insulating layer thereby being configured for electrically insulating the substrate from the second electrode corresponding thereto; wherein a top surface of the at least one first electrode and a top surface of the at least one functional layer are uncovered.
