Zero bias Schottky diode model for low RF input power (≤ 0 dBm at antenna input port) and moderate DC current (≥ 30 μA) RECtifying anTENNAs (RECTENNAs) is investigated. The model provides diode parameters at the desired output DC current level to be matched with the antenna so that optimum power transfer from antenna to the diode occurs. The model relies primarily on DC V-I diode characteristic...

In this study cardiac tissue is stimulated electrically through a small unipolar electrode. Numerical simulations predict that around an electrode are adjacent regions of depolarization and hyperpolarization. Experiments have shown that during pacing of resting cardiac tissue the hyperpolarization is often inhibited. Our goal is to determine if the inward rectifying potassium current (IK1) caus...

Today's circuit technology requires low-power transistors and diodes to extend Moore's law. While research has been focused on reducing power consumption of transistors, have not widely studied. Here, we report a low-power, thus steep-slope Schottky diode, with “cold metal” source. The barrier between metal electrode bulk MoS 2 enabled the diode behavior, IV curve originated from change in dens...

The results of measuring the charge-discharge characteristics solid-state thin-film lithium-ion batteries with a nanocomposite anode based on a-Si(Al) solid solution are presented. charging have feature in form step gentle branch U(t) curve. It has been suggested and substantiated that appearance is related to gradual compensation change hole conductivity electronic one as lithium concentration...

The IRK1 channel is inhibited by intracellular cations such as Mg(2+) and polyamines in a voltage-dependent manner, which renders its I-V curve strongly inwardly rectifying. However, even in excised patches exhaustively perfused with a commonly used artificial intracellular solution nominally free of Mg(2+) and polyamines, the macroscopic I-V curve of the channels displays modest rectification....

We have cloned a novel inward rectifier K+ channel (hIRK2) from a human frontal cortex cDNA library. The amino acid sequence of hIRK2 shares 60% and 40% identity with the mouse IRK1 and the rat ROMK1 channels, respectively. Xenopus oocytes injected with hIRK2 cRNA showed an inwardly rectifying K+ current that had a prominent 'N-shape' I-V curve and was blocked by extracellular Ba2+. The hIRK2 c...
