    Abstract: A dielectric material is disclosed comprising a plurality of substantially longitudinally oriented wires which are coupled together, wherein each of the wires includes a conductive core comprising a first material and one or more insulating shell layers comprising a compositionally different second material disposed about the core. In one embodiment, a dielectric layer is disclosed comprising a substrate comprising an insulating material having a plurality of nanoscale pores defined therein having a pore diameter less than about 100 nm, and a conductive material disposed within the nanoscale pores. Methods are also disclosed to create a dielectric material layer comprising, for example, providing a plurality of wires, wherein each of the wires includes a core comprising a first material and one or more insulating layers comprising a compositionally different second material disposed about the core; substantially longitudinally orienting said plurality of wires along their long axes; coupling the wires together; and depositing an insulating coating on at least one of a top and/or a bottom end of the wires.

    Abstract: 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.

    Abstract: Methods and apparatuses for nanoenabled memory devices and anisotropic charge carrying arrays are described. In an aspect, a memory device includes a substrate, a source region of the substrate, and a drain region of the substrate. A population of nanoelements is deposited on the substrate above a channel region, the population of nanolements in one embodiment including metal quantum dots. A tunnel dielectric layer is formed on the substrate overlying the channel region, and a metal migration barrier layer is deposited over the dielectric layer. A gate contact is formed over the thin film of nanoelements. The nanoelements allow for reduced lateral charge transfer. The memory device may be a single or multistate memory device. In a multistate memory device which comprises one or more quantum dots or molecules having a plurality of discrete energy levels, a method is disclosed for charging and/or discharging the device which comprises filling each of the plurality of discrete energy levels of each dot or molecule with one or more electrons, and subsequently removing individual electrons at a time from each discrete energy level of the one or more dots or molecules.
