    Abstract: Methods for fabrication of nanopillar field effect transistors are described. These transistors can have high height-to-width aspect ratios and be CMOS compatible. Silicon nitride may be used as a masking material. These transistors have a variety of applications, for example they can be used for molecular sensing if the nanopillar has a functionalized layer contacted to the gate electrode. The functional layer can bind molecules, causing an electrical signal in the transistor.

    Abstract: The present disclosure is directed toward systems and methods for measuring electric current in a multi-wire cable, as well as the apparent and real power associated with an electrical load connected to the cable. A probe comprising an array of small form-factor, high-speed magnetometers is operatively coupled with the cable such that the magnetometers partially surround the cable. Each magnetometer detects the composite magnetic field at its location, and this plurality of measurements is used to generate a magnetic-field map. The contributions of the current flow in each wire are identified by deconvolving the magnetic-field map, enabling their locations to be determined and monitoring of the current and power flow. A sensor included in the probe is used to determine the phase of the applied voltage. The phase difference between the voltage and current is then used to determine the real power dissipation of the load.

    Abstract: An infrared spectrometer for operation in the mid-infrared spectral range is presented, where the spectrometer includes a Bragg-mirror-based spectral filter that is operative for providing an interrogation signal whose spectral content is dispersed along a first direction at a filter aperture. The filter aperture is imaged through a sample by a thermal-imaging camera to create a focused image that is based on the interrogation signal and the absorption characteristics of the sample. As a result, embodiments in accordance with the present disclosure can be smaller, less complex, and less expensive than infrared spectrometers known in the prior art.
