Abstract: A vertically integrated multispectral imaging sensor includes a first metal contact layer on a substrate, an SiO2 layer on the first metal contact layer with a first detector element embedded in a hole therein, a first graphene layer that covers the first detector element, a second metal contact layer on the SiO2 layer on one side of the first graphene, an AlO3 layer on the SiO2 layer, in which a second detector element is embedded in a hole over the first graphene layer, a second graphene layer on the second detector element, and a third metal contact layer on the AlO3 layer adjacent to the second graphene layer. The first detector material is sensitive to a different wavelength band of the electromagnetic spectrum than the second detector material.

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: 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.
