摘要： The present invention is directed to methods of separating carbon nanotubes (CNTs) by their electronic type (e.g., metallic, semi-metallic, and semiconducting). Perhaps most generally, in some embodiments, the present invention is directed to methods of separating CNTs by bandgap, wherein such separation is effected by interacting the CNTs with a surface such that the surface interacts differentially with the CNTs on the basis of their bandgap, or lack thereof. In some embodiments, such methods can allow for such separations to be carried out in bulk quantities.

摘要： The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon surfaces. In some embodiments, such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. In some embodiments, the methods of the present invention include: (1) reacting a silicon surface with a functionalizing agent (such as oligo(phenylene ethynylene)) to form a functionalized silicon surface; (2) dispersing a quantity of CNTs in a solvent to form dispersed CNTs; and (3) reacting the functionalized silicon surface with the dispersed CNTs. The present invention is also directed to the novel compositions produced by such methods.

摘要： The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon or other surfaces, wherein such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. The present invention is also directed to the novel compositions produced by such methods. Previous work by Applicants has demonstrated covalent attachment of arenes via aryldiazonium salts to Si (hydride passivated single crystal or poly Si; or , p-doped, n-doped or intrinsic), GaAs, and Pd surfaces. In the case of Si, this provides a direct arene-Si bond with no intervening oxide. Applicants have also reported on the use of aryldiazonium salts for the direct covalent linkage of arenes to single wall carbon nanotubes (SWNTs) where the nanotubes can exist either as bundles or individual structures (when surfactant-wrapped). In some embodiments, the present invention is directed to a merger of these two technologies to afford the covalent attachment of individualized (unroped) SWNTs to Si surfaces.

摘要： Work from several laboratories has shown that metal nanofilaments cause problems in some molecular electronics testbeds. A new testbed for exploring the electrical properties of single molecules has been developed to eliminate the possibility of metal nanofilament formation and to ensure that molecular effects are measured. This metal-free system uses single-crystal silicon and single-walled carbon nanotubes as electrodes for the molecular monolayer. A direct Si-arylcarbon grafting method is used. Use of this structure with π-conjugated organic molecules results in a hysteresis loop with current-voltage measurements that are useful for an electronic memory device. The memory is non-volatile for more than 3 days, non-destructive for more than 1,000 reading operations and capable of more than 1,000 write-erase cycles before device breakdown. Devices without π-conjugated molecules (Si—H surface only) or with long-chain alkyl-bearing molecules produced no hysteresis, indicating that the observed memory effect is molecularly relevant.
摘要翻译：几个实验室的工作表明，金属纳米丝在一些分子电子测试台中引起问题。已经开发了用于探索单分子的电性质的新试验台，以消除金属纳米丝形成的可能性并确保测量分子效应。该无金属系统使用单晶硅和单壁碳纳米管作为分子单层的电极。使用直接的Si-芳基碳接枝方法。这种结构与共轭有机分子的结合产生了对电子存储器件有用的电流 - 电压测量的滞后回路。存储器非易失性超过3天，对于超过1,000次读取操作是非破坏性的，并且在器件故障之前能够进行超过1,000次写擦除周期。不具有共轭分子（仅含Si-H表面）或具有长链烷基的分子的器件不产生滞后，表明观察到的记忆效应具有分子相关性。
