摘要: A method of producing uniform multilayer graphene by chemical vapor deposition (CVD) is provided. The method is limited in size only by CVD reaction chamber size and is scalable to produce multilayer graphene films on a wafer scale that have the same number of layers of graphene throughout substantially the entire film. Uniform bilayer graphene may be produced using a method that does not require assembly of independently produced single layer graphene. The method includes a CVD process wherein a reaction gas is flowed in the chamber at a relatively low pressure compared to conventional processes and the temperature in the reaction chamber is thereafter decreased relatively slowly compared to conventional processes. One application for uniform multilayer graphene is transparent conductors. In processes that require multiple transfers of single layer graphene to achieve multilayer graphene structures, the disclosed method can reduce the number of process steps by at least half.

摘要翻译: 提供了通过化学气相沉积(CVD)制造均匀的多层石墨烯的方法。 该方法仅通过CVD反应室尺寸限制,并且可扩展以在基片上生产具有相同数量的石墨烯层的多晶石墨烯薄膜。 可以使用不需要组装独立生产的单层石墨烯的方法来生产均匀的双层石墨烯。 该方法包括CVD方法,其中与常规方法相比,反应气体在相对低的压力下在室中流动,然后与常规方法相比,反应室中的温度相对较慢地降低。 均匀多层石墨烯的一个应用是透明导体。 在需要多次转移单层石墨烯以实现多层石墨烯结构的方法中,所公开的方法可以将工艺步骤的数量减少至少一半。

摘要: The present invention relates generally to sub-microelectronic circuitry, and more particularly to nanometer-scale articles, including nanoscale wires which can be selectively doped at various locations and at various levels. In some cases, the articles may be single crystals. The nanoscale wires can be doped, for example, differentially along their length, or radially, and either in terms of identity of dopant, concentration of dopant, or both. This may be used to provide both n-type and p-type conductivity in a single item, or in different items in close proximity to each other, such as in a crossbar array. The fabrication and growth of such articles is described, and the arrangement of such articles to fabricate electronic, optoelectronic, or spintronic devices and components. For example, semiconductor materials can be doped to form n-type and p-type semiconductor regions for making a variety of devices such as field effect transistors, bipolar transistors, complementary inverters, tunnel diodes, light emitting diodes, sensors, and the like.

摘要: Systems, methods and devices for the efficient photocurrent generation in single- or multi-walled carbon nanotubes, which includes (SWNTs)/poly [3-hexylthiophene-2,5-diyl] (P3HT) hybrid photovoltaics, and exhibit the following features: photocurrent measurement at individual SWNT/P3HT heterojunctions indicate that both semiconducting (s-) and metallic (m-) SWNTs function as excellent hole acceptors; electrical transport and gate voltage dependent photocurrent indicate that P3HT p-dopes both s-SWNT and m-SWNT, and exciton dissociation is driven by a built-in voltage at the heterojunction. Some embodiments include a mm2 scale SWNT/P3HT bilayer hybrid photovoltaics using horizontally aligned SWNT arrays, which exhibit greater than 90% effective external quantum efficiency, among other things, which advantageously provide carbon nanomaterial based low cost and high efficiency hybrid photovoltaics.
