Abstract: Chemical sensors and methods of forming and making the same include an input terminal and an output terminal. A negative capacitance structure is configured to control a current passing horizontally from the input terminal to the output terminal, and has a first and second metal layer that are arranged vertically with respect to one another, and a ferroelectric layer positioned between the first and second metal layers. An electrode is in electrical contact with the negative capacitance structure, and is configured to change potential, to exceed a threshold, thereby triggering a discontinuous polarization change in the negative capacitance structure.

Abstract: A method for forming a nanostructure includes coating an exposed surface of a base layer with a patterning layer. The method further includes forming a pattern in the patterning layer including nano-patterned non-random openings, such that a bottom portion of the non-random openings provides direct access to the exposed surface of the base layer. The method also includes depositing a material in the non-random openings in the patterning layer, such that the material contacts the exposed surface to produce repeating individually articulated nano-scale features. The method includes removing remaining portions of the patterning layer. The method further includes forming an encapsulation layer on exposed surfaces of the repeating individually articulated nanoscale features and the exposed surface of the base layer.

Abstract: Methods of using and making chemical sensors include exposing a functionalized electrode to a substance to be tested. The functionalized electrode is electrically connected to a sensor having a piezoelectric element and a piezoresistive element. A voltage on the functionalized electrode controls a resistance of the piezoresistive element. A current is measured passing through the piezoresistive element. The presence of the analyte is determined based on the measured current.
