    Abstract: A method of forming a structure having selectively placed carbon nanotubes, a method of making charged carbon nanotubes, a bi-functional precursor, and a structure having a high density carbon nanotube layer with minimal bundling. Carbon nanotubes are selectively placed on a substrate having two regions. The first region has an isoelectric point exceeding the second region's isoelectric point. The substrate is immersed in a solution of a bi-functional precursor having anchoring and charged ends. The anchoring end bonds to the first region to form a self-assembled monolayer having a charged end. The substrate with charged monolayer is immersed in a solution of carbon nanotubes having an opposite charge to form a carbon nanotube layer on the self-assembled monolayer. The charged carbon nanotubes are made by functionalization or coating with an ionic surfactant.

    Abstract: A technique for embedding a nanotube in a nanopore is provided. A membrane separates a reservoir into a first reservoir part and a second reservoir part, and the nanopore is formed through the membrane for connecting the first and second reservoir parts. An ionic fluid fills the nanopore, the first reservoir part, and the second reservoir part. A first electrode is dipped in the first reservoir part, and a second electrode is dipped in the second reservoir part. Driving the nanotube into the nanopore causes an inner surface of the nanopore to form a covalent bond to an outer surface of the nanotube via an organic coating so that the inner surface of the nanotube will be the new nanopore with a super smooth surface for studying bio-molecules while they translocate through the nanotube.

    Abstract: A semiconductor device and a method of fabricating a semiconductor device are disclosed. Embodiments of the invention use a photosensitive self-assembled monolayer to pattern the surface of a substrate into hydrophilic and hydrophobic regions, and an aqueous (or alcohol) solution of a dopant compound is deposited on the substrate surface. The dopant compound only adheres on the hydrophilic regions. After deposition, the substrate is coated with a very thin layer of oxide to cap the compounds, and the substrate is annealed at high temperatures to diffuse the dopant atoms into the silicon and to activate the dopant. In one embodiment, the method comprises providing a semiconductor substrate including an oxide surface, patterning said surface into hydrophobic and hydrophilic regions, depositing a compound including a dopant on the substrate, wherein the dopant adheres to the hydrophilic region, and diffusing the dopant into the oxide surface of the substrate.
