    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.
