The potential impact of GaN-based high electron mobility transistor (HEMT) with two channel layers of GaN/InAlGaN is reported. Using two-dimensional and two-carrier device simulations, we investigate the device performance focusing on the electrical potential, electron concentration, breakdown voltage and transconductance (gm). Also, the results have been compared with structure of AlGaN/GaN HE...

We use a vertical double quantum dot (QD) to study spin blockade (SB) for the twoto five-electron states. SB observed for the twoand four-electron states is both assigned to Pauli exclusion with formation of a spin triplet state, and lifted by singlet-triplet admixing due to fluctuating nuclear field. SB observed for the five-electron state is caused by combined Pauli effect and Hund’s rule. We...

In various kinds of glomerulonephritis, alteration of anionic charge on the glomerular basement membrane (GBM) and podocytes has been controversial for more than decade. To elucidate the relation between glomerular protein leakage and anionic sites on the glomerular wall, we examined the distribution of anionic sites on the GBM and podocytes of rats with active Heymann nephritis (AHN). Urinalys...

Peroxidized low-density lipoprotein (p-LDL) has been previously demonstrated to be preferentially cytotoxic to certain malignant cells compared to normal cells of the same type. We present evidence that p-LDL is at least partially taken up through the LDL receptor and that it becomes localized in lysosomes. The integrity of lysosomes of p-LDL-treated cells is compromised, and leakage of their c...

Superior electronic and thermal properties have made InAlN/GaN high-electron-mobility transistors (HEMTs) an attractive candidate for power electronics applications. However, their high gate leakage current remains a serious challenge affecting the reliability and performance of these heterostructures. Leakage paths through dislocations or by percolation through inhomogeneities in the InAlN all...

By using an average heavy nuclei model, the effects of the electron screening on electron capture (EC) in core-collapse supernovae are investigated. A one-dimension code based on the Ws15M⊙ progenitor model is utilized to test the effects of electron screening during the collapsing process. The results show that, at high densities, the effects of EC on electron capture becomes significant. Duri...

introduction: the provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. root-end resection, preparation and obturation should provide an adequate apical seal. the aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of thes...

Electron transport activity at the cell surface of intact oat seedlings (Avena sativa L. cv Garry) was examined by measuring the oxidation and/or reduction of agents in the medium bathing the roots. Oxidation of NADH with or without added electron acceptors and reduction of ferricyanide by an endogenous electron donor were detected. The activities appear to be due to electron transfer at, or ac...
