Multichannel superconducting quantum interference device (SQUID) systems based on double relaxation oscillation SQUIDs (DROS) were developed for measuring magnetocardiography (MCG) and magnetoencephalography (MEG) signals. Since DROS provides large fluxto-voltage transfer coefficients, about 10 times larger than the DC SQUIDs, direct readout of the SQUID output was possible using compact roomte...

To determine the transporters responsible for toxic Na(+) influx in wheat (Triticum aestivum), root plasma membrane preparations were screened using the planar lipid bilayer technique as an assay for Na(+)-permeable ion channel activity. The predominant channel in the bilayer was a 44-pS channel that we called the nonselective cation (NSC) channel, which was nonselective for monovalent cations ...

The high temperature dependence of junctionless (JL) gate-all-around (GAA) poly-Si thin-film transistors (TFTs) with 2-nm-thick nanosheet channel is compared with that of JL planar TFTs. The variation of SS with temperature for JL GAA TFTs is close to the theoretical value (0.2 mV/dec/K), owing to the oxidation process to form a 2-nm-thick channel. The bandgap of 1.35 eV in JL GAA TFTs by fitti...

Any planar resistor (channel) close to a conducting layer left floating (gate) forms a capacitor C whose thermal voltage noise (kT/C noise) has a backgating effect on the sheet resistance of the channel that is a powerful source of 1/f resistance noise in planar resistors and, hence, in planar devices. This 1/f spectrum is created by the bias voltage VDS applied to the resistor, which is a dist...

The light-gated ion-channel protein is expected to be able to improve the performance of ionchannel devices for the multi-point screening and neural network devices based on the planar patch clamp. However, no studies with light-gated ion channels on a planar patch clamp have been reported. We constructed an incubation type of planar patch clamp biosensor using silicon-on-insulator substrates w...

In the presence of a low pH environment, the channel-forming T domain of diphtheria toxin undergoes a conformational change that allows for both its own insertion into planar lipid bilayers and the translocation of the toxin's catalytic domain across them. Given that the T domain contributes only three transmembrane segments, and the channel is permeable to ions as large as glucosamine(+) and N...

The current conduction process through a nanowire wrap-around-gate,B50nm channel diameter, silicon MOSFET has been investigated and compared with a B2mm wide slab, B200nm thick silicon (SOI) top-only-gate planarMOSFETwith otherwise similar doping profiles, gate length and gate oxide thickness. The experimental characteristics of the nanowire and planar MOSFETs were compared with theoretical sim...
