Using saturated alkyl chain series with a dithiol anchor group, we systematically examined the intrinsic charge transport of single-molecule junctions in an electromigrated nanogap electrode. The saturated alkyl molecular system constitutes an important control series in molecular transport experiments to corroborate valid molecular junctions, because molecular energy levels remain nearly uncha...

A new approach to perform measurement of potentials in high voltage levels using electrooptical Pockels sensors is presented here. This paper describes an application of the White Light Interferometry technique to a high voltage optical fiber measurement system. In this system the information is encoded in the spectrum of the light, allowing the measurement to be independent of the optical powe...

We demonstrate experimentally that a hybrid single-electron transistor with superconducting leads and a normal-metal island can be refrigerated by an alternating voltage applied to the gate electrode. The simultaneous measurement of the dc current induced by the rf gate through the device at a small bias voltage serves as an in situ thermometer.

We demonstrate a new approach to impedance measurement on digital microfluidics chips for the purpose of simple, sensitive, and accurate volume and liquid composition measurement. Adding only a single series resistor to existing AC droplet actuation circuits, the platform is simple to implement and has negligible effect on actuation voltage. To accurately measure the complex voltage across the ...

This paper presents a methodology for the classification of power system voltage stability, the trajectory of which to instability is monotonic, using an interior point method based support vector machine (IPMSVM). The SVM based voltage stability classifier can provide real-time stability identification only using the local measurement data, without the topological information conventionally used.

Accurate estimation of model parameters and state of charge (SoC) is crucial for the lithium-ion battery management system (BMS). In this paper, the stability of the model parameters and SoC estimation under measurement uncertainty is evaluated by three different factors: (i) sampling periods of 1/0.5/0.1 s; (ii) current sensor precisions of ±5/±50/±500 mA; and (iii) voltage sensor precisions o...

For a primary substation (P/S), there are many typical methods to control voltage and reactive power such as adjusting the generator mode, switching shunt capacitor (SC), adjusting on-load tap changer (OLTC), and switching shunt reactor (SR). In this study, a graphical user interface (GUI) is designed combining with nine-area diagram to observe the relationship between voltage and reactive powe...

The advantage of this method involves controlling the flow of current through all the connections – especially those used to measure the voltage. The measurement current flows through one set of connections, usually those that are farthest apart. If these connections are resistive (i.e., the connections are poor) there will be significant voltage drop across them. However, this voltage drop doe...

The signal processing circuit of shunt type current sensor is directly coupled with the high voltage electric circuit so that the common-mode interference signal conditioning becomes a problem. This paper proposes a high-voltage isolation current sensor employs modulation and demodulation which is based on shunt output signal. There is an electrical isolation is set between the high voltage and...

A New electrical method, using charge-pumping (CP) technique under bias thermal stress (BTS), has been described in this paper. This technique is based on the charge-pumping measurement which in turn used to extract the flat-band voltage before and after an applied bias voltage at high temperature. The obtained flat band voltage shift, that is due to redistribution of the mobile ionic charges, ...
