    Abstract: Embodiments of the invention are directed to methods and resulting structures for enhancing drive current and increasing device yield in n-type carbon nanotube field effect transistors (CNT FETs) with scaled contacts using a wetting layer. In some embodiments of the invention, a nanotube is formed over a surface of a substrate. An insulating layer is formed over the nanotube such that end portions of the nanotube are exposed. A low work function metal is formed over the end portions of the nanotube and a wetting layer is formed between the low work function metal and the nanotube.

    Abstract: A drug delivery system includes a substrate, an integrated sensor disposed on the substrate, a drug delivery element disposed on the substrate, and a control unit coupled to the integrated sensor and the drug delivery element. The integrated sensor includes first and second electrodes disposed on a first surface of the substrate. The drug delivery element includes a reservoir disposed on the first surface of the substrate, a thermally active polymer enclosing the reservoir, and a heating coil disposed over the thermally active polymer. The control unit is configured to measure a biological parameter by measuring a voltage difference between the first and second electrodes of the integrated sensor, and to apply a trigger signal to the heating coil of the drug delivery element responsive to the measured biological parameter indicating a designated condition to heat up the thermally active polymer to selectively release a drug from the reservoir.

    Abstract: A semiconductor device includes a substrate that extends along a first direction to define a length and second direction perpendicular to the first direction to define a height. The substrate includes a dielectric layer and at least one gate stack formed on the dielectric layer. A source contact is formed adjacent to a first side of the gate stack and a drain contact formed adjacent to an opposing second side of the gate stack. A carbon nanotube is formed on the source contact and the drain contact. A first portion of the nanotube forms a source. A second portion forms a drain. A third portion is interposed between the source and drain to define a gate channel that extends along the first direction. The source and the drain extend along the second direction and have a greater length than the gate channel.
