In this paper we report a study on the small signal characterization and simulation of Single Halo (SH) thin film Silicon-on-Insulators (SOI) nMOSFETs for analog and mixed signal applications. The single halo structure has a high pocket impurity concentration near the source end of the channel and low impurity concentration in the rest of the channel. Besides excellent DC output characteristics...

The effect of impurities which induce local interlayer tunneling in bilayer exciton condensates is discussed. We show that a localized single-fermion bound state emerges inside the gap for any strength of impurity scattering and calculate the dependence of the impurity state energy and wave function on the potential strength. We show that such an impurity-induced single-fermion state enhances t...

We review recent developments in our understanding of how impurities influence the electronic states in the bulk of superconductors. Our focus is on the quasi-localized states in the vicinity of impurity sites in conventional and unconventional superconductors and our goal is to provide a unified framework for their description. The non-magnetic impurity resonances in unconventional superconduc...

An analytical model is proposed for the random dopant fluctuation (RDF) in a symmetric double-gate metal-oxidesemiconductor field-effect-transistor (DG MOSFET) in the subthreshold region. Unintended impurity dopants cannot be absolutely prevented during the device fabrication; hence, it is important to analytically model the fluctuations in the electrical characteristics caused by these impurit...

abstract salinity is one of the major abiotic challenges influencing plant productivity worldwide. to examine the response of two alfalfa cultivars (bami and hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mm l-1 nacl), a glasshouse experiment was conducted at the college of agriculture, shiraz university, shiraz, iran in 2008. the results showed that in bami (which appeared...

We study a model of a d-wave superconductor with strong potential scatterers in the presence of antiferromagnetic correlations and apply it to experimental nuclear magnetic resonance NMR results on Zn impurities in the superconducting state of YBa2Cu3O7− . We then focus on the contribution of impurity-induced paramagnetic moments, with Hubbard correlations in the host system accounted for in Ha...

2014 A model for the dipole force tensor P arising from the inclusion of interstitial hydrogen in 03B1-palladium hydrides is given in terms of the electronic structure of the alloy. The electronic structure of the impurity is described in the tight-binding approximation of the Green function formalism. A subtle compensation between attractive (band terms) and repulsive (electron-electron and io...

By employing atomistic computer simulations with empirical potential and density functional force models, we study B/N ion implantation onto carbon nanotubes. We simulate irradiation of single-walled nanotubes with B and N ions and show that up to 40% of the impinging ions can occupy directly the sp2 positions in the nanotube atomic network. We further estimate the optimum ion energies for dire...
