    摘要: An imprinting apparatus and method of fabrication provide a mold having a pattern for imprinting. The apparatus includes a semiconductor substrate polished in a [110] direction. The semiconductor substrate has a (110) horizontal planar surface and vertical sidewalls of a wet chemical etched trench. The sidewalls are aligned with and therefore are (111) vertical lattice planes of the semiconductor substrate. The semiconductor substrate includes a plurality of vertical structures between the sidewalls, wherein the vertical structures may be nano-scale spaced apart. The method includes wet etching a trench with spaced apart (111) vertical sidewalls in an exposed portion of the (110) horizontal surface of the semiconductor substrate along (111) vertical lattice planes. A chemical etching solution is used that etches the (111) vertical lattice planes slower than the (110) horizontal lattice plane. The method further includes forming the imprinting mold.

    摘要: Self-assembled nanowires are provided, comprising nanowires of a first crystalline composition formed on a substrate of a second crystalline composition. The two crystalline materials are characterized by an asymmetric lattice mismatch, in which in the interfacial plane between the two materials, the first material has a close lattice match (in any direction) with the second material and has a large lattice mismatch in all other major crystallographic directions with the second material. This allows the unrestricted growth of the epitaxial crystal in the first direction, but limits the width in the other.

    摘要: Self-organized, or self-assembled, nanowires of a first composition may be used as an etching mask for fabrication of nanowires of a second composition. The method for forming such nanowires comprises: (a) providing an etchable layer of the second composition and having a buried insulating layer beneath a major surface thereof; (b) growing self-assembled nanowires on the surface of the etchable layer; and (c) etching the etchable layer anisotropically down to the insulating layer, using the self-assembled nanowires as a mask. The self-assembled nanowires may be removed or left. In either event, nanowires of the second composition are formed. The method enables the formation of one-dimensional crystalline nanowires with widths and heights at the nanometer scale, and lengths at the micrometer scale, which are aligned along certain crystallographic directions with high crystal quality. Further, the method of the present invention avoids traditional lithography methods, minimizes environmental toxic chemicals usage, simplifies the manufacturing processes, and allows the formation of high-quality one-dimensional nanowires over large areas.

    摘要: Configurable electronic circuits comprise arrays of cross-points of one layer of metal/semiconductive nanoscale lines crossed by a second layer of metal/semiconductive nanoscale lines, with a configurable layer between the lines. Methods are provided for altering the thickness and/or resistance of the configurable layer by oxidation or reduction methods, employing a solid material as the configurable layer. Specifically a method is provided for configuring nanoscale devices in a crossbar array of configurable devices comprising arrays of cross-points of a first layer of nanoscale lines comprising a first metal or a first semiconductor material crossed by a second layer of nanoscale lines comprising a second metal or a second semiconductor material. The method comprises: (a) forming the first layer on a substrate; (b) forming a solid phase of a configurable material on the first layer at least in areas where the second layer is to cross the first layer; (c) forming the second layer on the configurable material, over the first layer; and (d) changing a property of the configurable material to thereby configure the nanoscale devices.

    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.
