Ab-initio full-potential linearized augmented plane wave (FLAPW) calculations have been used to study the influence of the interface morphology and, notably, of the exchange reaction on the electronic properties of Al/GaN (100) interfaces. Although the detailed mechanism is not understood, the exchange reaction has been purported to influence the Schottky barrier height as a result of the forma...

Schottky barrier contact has been fabricated by thermal deposition of Al on (100) p-Ge (impurity concentratioñ1010/cm3 at 80K) that shows n-type conductivity above 180K due to thermally generated carriers. Both p and Ge exhibits ideal behavior with low reverse current near unity ideality factors obtained from the linear form temperature dependent current-voltage (I–V) characteristics. The diode...

A graphene Schottky contact was fabricated on an AlGaN/GaN heterostructure and subsequently analyzed. The calculated experimentally measured barrier heights (SBHs) determined using the theoretical Schottky–Mott model, thermionic emission temperature-dependent current–voltage measurement, capacitance–voltage measurement were observed to be inconsistent, which attributed ambiguities in both area ...

High contact resistance (RC) between 3D metallic conductors and single-layer 2D semiconductors poses major challenges toward their integration in nanoscale electronic devices. While experiments the large RC values can be partly due to defects, ab initio simulations suggest that, even defect-free structures, interaction metal semiconductor orbitals induce gap states that pin Fermi level band gap...

It is known that using Boltzmann-Gibbs statistics, Bekenstein-Hawking entropy SHB, and the quasinormal modes of black holes, one finds lowest value spin jmin=1. In this paper, we determine jmin, non-extensive entropies depend only on probability (known as Obregon's have been derived from superstatistics). We also calculate jmin for a set free parameters are written in terms SBH. find depends ar...

This study investigated the importance of the male sex hormone testosterone on salt-induced hypertension, renal alpha(2)-adrenoceptor subtype distribution, and gene expression in salt-sensitive (SBH) male Sabra rats. Comparisons of blood pressure and renal alpha(2)-adrenoceptor subtype gene expression and receptor densities have been made among sham-operated rats, and gonadectomized rats treate...

Soybean hulls (SBHs) have been fed to cattle pasturing on endophyte-infected tall fescue in attempts to increase rate of gain. Literature reports indicated some symptoms associated with fescue toxicosis were ameliorated by the use of steroidal implants containing estradiol (E2) and progesterone [implantation (IMP)], feeding SBHs, or the combination of the two. While the mechanism for ameliorati...

Abstract Accretion disks of active galactic nuclei (AGNs) have been proposed as promising sites for producing both (stellar-mass) compact object mergers and extreme mass ratio inspirals. Along with disk-assisted migration, ambient gas inevitably accretes onto objects. In previous studies, it was commonly assumed that either an Eddington rate or a Bondi takes place, although they can differ by s...

Thermochemical heat storage (TCHS) in salt hydrates attracts increasing interest due to the high energy density combined with loss-free storage. Strontium bromide hexahydrate (SBH), and composites thereof, are often suggested as suitable materials for this application. Although many aspects of SBH have been thoroughly investigated, very little has done on fundamental hydration reaction interact...
