    摘要： In a method for fabricating a graphene structure, there is formed on a fabrication substrate a pattern of a plurality of distinct graphene catalyst materials. In one graphene synthesis step, different numbers of graphene layers are formed on the catalyst materials in the formed pattern. In a method for fabricating a graphene transistor, on a fabrication substrate at least one graphene catalyst material is provided at a substrate region specified for synthesizing a graphene transistor channel and at least one graphene catalyst material is provided at a substrate region specified for synthesizing a graphene transistor source, and at a substrate region specified for synthesizing a graphene transistor drain. Then in one graphene synthesis step, at least one layer of graphene is formed at the substrate region for the graphene transistor channel, and at the regions for the transistor source and drain there are formed a plurality of layers of graphene.

    摘要： Provided are methods of printing a pattern of charge on a substrate surface, such as by electrohydrodynamic (e-jet) printing. The methods relate to providing a nozzle containing a printable fluid, providing a substrate having a substrate surface and generating from the nozzle an ejected printable fluid containing net charge. The ejected printable fluid containing net charge is directed to the substrate surface, wherein the net charge does not substantially degrade and the net charge retained on the substrate surface. Also provided are functional devices made by any of the disclosed methods.

    摘要： Provided are high-resolution electrohydrodynamic inkjet (e-jet) printing systems and related methods for printing functional materials on a substrate surface. In an embodiment, a nozzle with an ejection orifice that dispenses a printing fluid faces a surface that is to be printed. The nozzle is electrically connected to a voltage source that applies an electric charge to the fluid in the nozzle to controllably deposit the printing fluid on the surface. In an aspect, a nozzle that dispenses printing fluid has a small ejection orifice, such as an orifice with an area less than 700 μm2 and is capable of printing nanofeatures or microfeatures. In an embodiment the nozzle is an integrated-electrode nozzle system that is directly connected to an electrode and a counter-electrode. The systems and methods provide printing resolutions that can encompass the sub-micron range.
