Two ee colliders, VEPP-4M and VEPP2000, are taking data at the Budker INP in Novosibirsk, Russia. KEDR detector at the VEPP-4M collider continues deliver precision measurements of the charmonium family. Results of the ψ(2S ) and ψ(3770) study are presented. Two energy scans of a center-of-mass energy range from 1 GeV to 2 GeV has been performed by the VEPP2000 collider with an integrated lumino...

in this paper, we examine the effect of the energy difference between the l- and the -valleys in compound semiconductor materials, carrier effective mass, and the scattering processes on the electron transport characteristics in mesfets. to do this, we use the monte carlo simulation to demonstrate the superiority of the ingaas mesfet, made on a semi-insulating inp substrate, over both inp and ...

The authors report the self-organized growth of InAs/ InAlAs quantum wires on nominal 001 InP substrate and 001 InP substrates misoriented by 2°, 4°, and 8° towards both −110 and 110 . The influence of substrate misorientation on the structural and optical properties of these InAs/ InAlAs quantum wires is studied by transmission electron microscopy and photoluminescence measurements. Compared w...

We report reproducible fabrication of InP-InAsP nanowire light-emitting diodes in which electron-hole recombination is restricted to a quantum-dot-sized InAsP section. The nanowire geometry naturally self-aligns the quantum dot with the n-InP and p-InP ends of the wire, making these devices promising candidates for electrically driven quantum optics experiments. We have investigated the operati...

in this article, we suggested a novel design of polarization splitter based on coupler waveguide on inp substrate at 1.55mm wavelength. photonic crystal structure is consisted of two dimensional (2d) air holes embedded in inp/ingaasp material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. the photonic band gap (pbg) of this structure is determined using t...

A unique wafer-scale self-organization process for generation of InP nanopillars is demonstrated, which is based on maskless ion-beam etching (IBE) of InP developed to obtain the nanopillars, where the height, shape, and orientation of the nanopillars can be varied by controlling the processing parameters. The fabricated InP nanopillars exhibit broadband suppression of the reflectance, 'black I...

Ice nucleating particles (INP) active at a few degrees below 0°C are produced by a range of organisms and released into the environment. They may affect cloud properties and precipitation when becoming airborne. So far, our knowledge about sources of biological INP is based on grab samples of vegetation, soil or water studied in the laboratory. By combining measurements of INP concentrations in...

Peripheral circulation is severely compromised in the advanced stages of peripheral arterial disease. Recently, it was shown that the application of -40 mmHg intermittent negative pressure (INP) to the lower leg and foot enhances macro- and microcirculation in healthy volunteers. In this case report, we describe the effects of INP treatment on four patients with lower limb ischemia and hard-to-...

Epitaxial layers of p-type indium phosphide (InP) have been grown by low pressure, metal organic chemical vapour deposition (LP-MOCVD) using diethylzinc (DEZn) as the p-dopant source. Proposed zinc-associated InP point defects and experimental DEZn doping data were used to formulate a point-defect equilibrium model of the Zn doping process of MOCVD InP. The model equation is contrasted with the...

Radiative corrections to QCD amplitudes in the quasi-multi-Regge kinematics are interesting in particular since the Reggeized form of these amplitudes is used in the derivation of the NLO BFKL. This form is a hypothesis which must be at least carefully checked, if not proved. We calculate the radiative corrections in the one-loop approximation using the s-channel unitarity. Compatibility of the...
