    摘要: Methods of doping nanostructures, such as nanowires, are disclosed. The methods provide a variety of approaches for improving existing methods of doping nanostructures. The embodiments include the use of a sacrificial layer to promote uniform dopant distribution within a nanostructure during post-nanostructure synthesis doping. In another embodiment, a high temperature environment is used to anneal nanostructure damage when high energy ion implantation is used. In another embodiment rapid thermal annealing is used to drive dopants from a dopant layer on a nanostructure into the nanostructure. In another embodiment a method for doping nanowires on a plastic substrate is provided that includes depositing a dielectric stack on a plastic substrate to protect the plastic substrate from damage during the doping process. An embodiment is also provided that includes selectively using high concentrations of dopant materials at various times in synthesizing nanostructures to realize novel crystallographic structures within the resulting nanostructure.

    摘要: Methods, systems, and apparatuses for electronic devices having improved gate structures are described. An electronic device includes at least one nanowire. A gate contact is positioned along at least a portion of a length of the at least one nanowire. A dielectric material layer is between the gate contact and the at least one nanowire. A source contact and a drain contact are in contact with the at least one nanowire. At least a portion of the source contact and/or the drain contact overlaps with the gate contact along the nanowire the length. In another aspect, an electronic device includes a nanowire having a semiconductor core surrounded by an insulating shell layer. A ring shaped first gate region surrounds the nanowire along a portion of the length of the nanowire. A second gate region is positioned along the length of the nanowire between the nanowire and the substrate. A source contact and a drain contact are coupled to the semiconductor core of the nanowire at respective exposed portions of the semiconductor core.
