    Abstract: A fin structure including a vertical alternating stack of a first isoelectric point material layer having a first isoelectric point and a second isoelectric material layer having a second isoelectric point less than the first isoelectric point is formed. The first and second isoelectric point material layers become oppositely charged in a solution with a pH between the first and second isoelectric points. Negative electrical charges are imparted onto carbon nanotubes by an anionic surfactant to the solution. The electrostatic attraction causes the carbon nanotubes to be selectively attached to the surfaces of the first isoelectric point material layer. Carbon nanotubes are attached to the first isoelectric point material layer in self-alignment along horizontal lengthwise directions of the fin structure. A transistor can be formed, which employs a plurality of vertically aligned horizontal carbon nanotubes as the channel.

    Abstract: A self-assembled semiconductor nanostructure includes a core and a shell, wherein one of the core or the shell is rich in a strained component and the other of the core or the shell is rich in an unstrained component, wherein the nanostructure is a quantum dot or a nanowire. A method includes growing a semiconductor alloy structure on a substrate using a growth mode that produces a semiconductor alloy structure having a self-assembled core and shell and allowing the structure to equilibrate such that one of the core or the shell is strained and the other is unstrained. Another method includes growing at least one semiconductor alloy nanostructures on a substrate, wherein the nanostructure comprises a strained component and an unstrained component, and controlling a compositional profile during said growing such that a transition between the strained component and an unstrained component is substantially continuous.

    Abstract: A process is provided for fabricating rounded three-dimensional germanium active channels for transistors and sensors. For forming sensors, the process comprises providing a crystalline silicon substrate; depositing an oxide mask on the crystalline silicon substrate; patterning the oxide mask with trenches to expose linear regions of the silicon substrate; epitaxially grow germanium selectively in the trenches, seeded from the silicon wafer; optionally etching the SiO2 mask partially, so that the cross section resembles a trapezoid on a stem; and annealing at an elevated temperature. The annealing process forms the rounded channel. For forming transistors, the process further comprises depositing and patterning a gate oxide and gate electrode onto this structure to form the gate stack of a MOSFET device; and after patterning the gate, implanting dopants into the source and drain located on the parts of the germanium cylinder on either side of the gate line.
