It is assumed that proton decays into Planck neutrinos. The energy of the Planck neutrino is equal to the Planck mass in the preferred rest frame. In the frame moving relative to the preferred rest frame the energy of the Planck neutrino reduces by the corresponding Lorentz factor. The lifetime of proton depends on the kinetic energy of proton relative to the preferred rest frame. The time requ...

We study the mobility and collective diffusion of mutually interacting adparticles on stepped surfaces through Monte Carlo simulations. We consider the case of nearest-neighbor repulsive interactions and different binding energies at the step edges in the disordered phase. We find that the coverage dependence of diffusion across the steps is sensitive to the adparticle interaction energy. For s...

Both single electron and hole quantum dot transistors in silicon-on-insulator were fabricated and characterized. The quantum dots were formed using electron-beam nanolithography and reactive ion etching. The single electron quantum dot transistors show the oscillation of the drain current as a function of the gate voltage at temperatures up to 170 K and drain biases up to 80 mV. The oscillation...

This review reflects the status (in early 1973) of the problem of producing photoemitters and secondary and field emitters based on a new principle, that of obtaining semiconductor structures with negative electron affinity (ΝΕΑ). The energy level scheme of the surface region of a semiconductor with ΝΕΑ is examined, as well as the conditions for its realization. The main theoretical concepts of...

Spectroscopic diagnostic technique are applied for the determination of excitation temperature Texc and electron density in Air Acetylene premixed laminar flame. A group of FeI spectral lines has been used to estimate Texc using Boltzmann plot. Electron number density was determined from atom ion line pairs for Cd and Zn using Saha Boltzmann equation after substitution the obtained value of exc...

We have theoretically investigated the time-evolution of electron transport from a twodimensional electron system (2DES) to a quantum dot (QD). We clearly showed that the coherent electron transport is remarkably modified depending on the initial electronic state in the 2DES. The electron transport from the 2DES to the QD is strongly enhanced when the initial state of electron in the 2DES is lo...

two organic compounds (sc-23=(e)-2-cyano-3-(2,3-dimethoxyphenyl) acrylic acid and sc-25=(e)-2-cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. they shows a short-circuit current density (jsc) of 2.08 and 1.81 ma cm-2, an open circuit voltage (voc)...

DFT-GGA method of Perdew-Burke-Ernzerhof (PBE) is used with aug-cc-PVTZ, 6-311++G**, and Def2-TZVP large basis sets to study the hydrogen bond interactions between oxygen lone pair as a donor electron with hydrogen atom connected to the aniline’s nitrogen as an electron acceptor (H2O···HNH-Ph), and nitrogen lone pair with hydrogen of water molecule (Ph-H2N···HOH...

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited despite the fact that nature witnesses. Scientific research reveals strong analogy between electron and photon. Atoms of solid state that execute suitable electron transitions excite electron while absorbing heat energy at shunt level. De-excitation of an electron back to or...
