    摘要: A mold with a protruding pattern is provided that is pressed into a thin polymer film via an imprinting process. Controlled connections between nanowires and microwires and other lithographically-made elements of electronic circuitry are provided. An imprint stamp is configured to form arrays of approximately parallel nanowires which have (1) micro dimensions in the X direction, (2) nano dimensions and nano spacing in the Y direction, and three or more distinct heights in the Z direction. The stamp thus formed can be used to connect specific individual nanowires to specific microscopic regions of microscopic wires or pads. The protruding pattern in the mold creates recesses in the thin polymer film, so the polymer layer acquires the reverse of the pattern on the mold. After the mold is removed, the film is processed such that the polymer pattern can be transferred on a metal/semiconductor pattern on the substrate.

    摘要: A nano-colonnade structure-and methods of fabrication and interconnection thereof utilize a nanowire column grown nearly vertically from a (111) horizontal surface of a semiconductor layer to another horizontal surface of another layer to connect the layers. The nano-colonnade structure includes a first layer having the (111) horizontal surface; a second layer having the other horizontal surface; an insulator support between the first layer and the second layer that separates the first layer from the second layer. A portion of the second layer overhangs the insulator support, such that the horizontal surface of the overhanging portion is spaced from and faces the (111) horizontal surface of the first layer. The structure further includes a nanowire column extending nearly vertically from the (111) horizontal surface to the facing horizontal surface, such that the nanowire column connects the first layer to the second layer.

    摘要: A method for tailoring at least portions of an exposed non-planar layered surface of a conductive layer formed on a substrate having a first surface roughness to provide the exposed surface with a second surface roughness. The method includes: forming the conductive layer on the substrate; and tailoring at least portions of the exposed surface of the conductive layer in a plasma to at least smooth the exposed surface of the conductive layer, whereby the second surface roughness is essentially the same as the first surface roughness.

    摘要: A method is provided for fabricating molecular electronic devices comprising at least a bottom electrode and a molecular switch film on the bottom electrode. The method includes forming the bottom electrode by a process including: cleaning portions of the substrate where the bottom electrode is to be deposited; pre-sputtering the portions; depositing a conductive layer on at least the portions; and cleaning the top surface of the conductive layer. Advantageously, the conductive electrode properties include: low or controlled oxide formation (or possibly passivated), high melting point, high bulk modulus, and low diffusion. Smooth deposited film surfaces are compatible with Langmuir-Blodgett molecular film deposition. Tailored surfaces are further useful for SAM deposition. The metallic nature gives high conductivity connection to molecules. Barrier layers may be added to the device stack, i.e., Al2O3 over the conductive layer.

    摘要: A field-emission ion source in which, under the influence of an electric field, ions are released from a metal or metal alloy present in an enclosed space in the liquid state. The ions are emitted from this space through a very narrow slit. This slit may be straight or curved. The field-emission ion source can be used in an ion thruster apparatus comprising an emitter module, an electrode system, and a power supply unit. A plurality of emitter modules can be combined to form an ion thruster apparatus having a greater ion current output. Instead of a liquid metal as the propellant, a metal in the solid phase can be supplied to the emitter module, which metal is melted in the emitter module.
