A detailed three-dimensional (3-D) statistical “atomistic” simulation study of fluctuation-resistant sub-0.1m MOSFET architectures with epitaxial channels and delta doping is presented. The need for enhancing the fluctuation resistance of the sub-0.1m generation transistors is highlighted by presenting summarized results from atomistic simulations of a wide range of conventional devices with un...

In this paper, kinetics of DC electrophoretic deposition EPD of carbon nanotubes CNTs is investigated. Carbon nanotubes suspended in pure ethanol with addition of magnesium nitrate was used as deposition media. The effect of main EPD parameters such as deposition time, applied voltage and the CNT concentration on deposit yield was investigated. The variation of current density vs. time and the ...

Neurones are noisy elements. Noise arises from both intrinsic and extrinsic sources, and manifests itself as fluctuations in the membrane potential. These fluctuations limit the accuracy of a neurone's output but have also been suggested to play a computational role. We present a detailed study of the amplitude and spectrum of voltage noise recorded at the soma of layer IV-V pyramidal neurones ...

The voltage-gated potassium channel Kv7.1 and its auxiliary subunit KCNE1 are expressed in the heart and give rise to the major repolarization current. The interaction of Kv7.1 with the single transmembrane helix of KCNE1 considerably slows channel activation and deactivation, raises single-channel conductance, and prevents slow voltage-dependent inactivation. We built a Kv7.1-KCNE1 model-struc...

The cellular basis of reactive oxygen intermediate-induced arrhythmias was investigated in isolated rabbit ventricular cells using the whole-cell voltage- and current-clamp techniques. Singlet oxygen and superoxide were generated by the photoactivation of rose bengal. Single ventricular cells exposed to rose bengal (10-100 nM) exhibited spontaneous membrane potential fluctuations at plateau pot...
