  • Publication number: 20140002824
    Abstract: A method for forming a nanostructure penetrating a layer and the device made thereof is disclosed. In one aspect, the device has a substrate, a layer present thereon, and a nanostructure penetrating the layer. The nanostructure defines a nanoscale passageway through which a molecule to be analyzed can pass through. The nanostructure has, in cross-sectional view, a substantially triangular shape. This shape is particularly achieved by growth of an epitaxial layer having crystal facets defining tilted sidewalls of the nanostructure. It is highly suitably for use for optical characterization of molecular structure, particularly with surface plasmon enhanced transmission spectroscopy.

  • Publication number: 20130333741
    Abstract: Described herein is a low-voltage unidirectional bypass element connected across a solar cell and operable to allow current to flow when the operation of the solar cell is suspended. The bypass element includes a single field effect transistor connected between first and second terminals as a switch, and a detection circuit for detecting suspension of the solar cell's operation and activating the switch to bypass the solar cell in the event of its operation suspension. Diodes are connected in parallel with the normally-open switch and receive current, when the solar cell's operation is suspended, to trigger operation of the detection circuit. The detection circuit includes a charge pump, a timer circuit, a control generation unit and a switch control circuit. The switch control circuit generates a control signal to close the switch and to allow current to bypass the solar cell.

  • Publication number: 20130335744
    Abstract: A method is disclosed for determining the inactive doping concentration of a semiconductor region using a PMOR method. In one aspect, the method includes providing two semiconductor regions having substantially the same known as-implanted concentration but known varying junction depths. The method includes determining on one of these semiconductor regions the as-implanted concentration. The semiconductor regions are then partially activated. PMOR measures are then performed on the partially activated semiconductor regions to measure (a) the signed amplitude of the reflected probe signal as function of junction depth and (b) the DC probe reflectivity as function of junction depth. The method includes extracting from these measurements the active doping concentration and then calculating the inactive doping concentration using the determined total as-implanted concentration and active doping concentration.

  • Publication number: 20130187113
    Abstract: A nonvolatile memory device is disclosed comprising a metal-to-insulator transition material thermally coupled to a Peltier element. During programming, a selected current is flowing through the Peltier element, the level thereof determining whether the temperature of the Peltier element and hence of the thermally coupled metal-to-insulator transition material decreases or increases. In response to this temperature change, the metal-to-insulator transition material will change from one electrical conduction phase to another. The memory device is read by applying current through the metal-to-insulator transition material, the current level being selected to maintain the phase of the metal-to-insulator transition material.

  • Publication number: 20130187669
    Abstract: A built-in self-calibration system and method for a micro-mirror array device, for example, operating as a variable focal length lens is described. The calibration method comprises determining a capacitance value for each micro-mirror element in the array device at a number of predetermined reference angles to provide a capacitance-reference angle relationship. From the capacitance values, an interpolation step is carried to determine intermediate tilt angles for each micro-mirror element in the array. A voltage sweep is applied to the micro-mirror array and capacitance values, for each micro-mirror element in the array, are measured. For a capacitance value that matches one of the values in the capacitance-reference angle relationship, the corresponding voltage is linked to the associated tilt angle to provide a voltage-tilt angle characteristic which then stored in a memory for subsequent use.

  • Publication number: 20130187680
    Abstract: A complementary logic technology is disclosed whereby a logic gate comprises at least two metal-to-insulator transition (MIT) elements and at least two thermoelectric elements, each MIT element being thermally coupled to a corresponding thermoelectric element. In logic gates, each electric signal at an input terminal of a logic gate is first converted into two complementary thermal signals, and these thermal signals in turn determine the status of the output terminal of the logic gate, thereby generating an electrical output signal inverse to the electrical input signal or an output signal which is a Boolean operation on input signals. The parallel connection(s) of thermoelectric elements of the logic gate is used to create corresponding thermal signals for each electrical input signal. The MIT elements of the logic gate are then arranged to, in response to the associated thermal signals, execute a Boolean operation.
