We report the results of molecular dynamics simulations of electron-transfer activation parameters of plastocyanin metalloprotein involved as an electron carrier in natural photosynthesis. We have discovered that slow, non-ergodic conformational fluctuations of the protein, coupled to hydrating water, result in a very broad distribution of donor-acceptor energy gaps far exceeding those observed...

The performance of carbon nanotube field-effect transistors is analyzed numerically, using the non-equilibrium Green's function formalism. The effect of electron-phonon scattering on both the DC and switching response of these devices is studied. For the calculation of the switching response, the quasi-static approximation is assumed. The role of the electron-phonon coupling strength and phonon...

High-energy, multi-component plasmas in which pair creation and annihilation, leptonlepton scattering, lepton-proton scattering, and Comptonization all contribute to establishing the particle and photon distributions, are present in a broad range of compact astrophysical objects. The different constituents are often not in equilibrium with each other, and this mixture of interacting particles a...

The Electron-Beam Plasma (EBP) is generated by injecting an electron beam (EB) into a gaseous medium. The EBP composition is complex: generally it contains molecules, atoms, radicals and ions in stable and excited states, plasma electrons and injected beam electrons as well. At moderate pressures (Pm <10 kPa) the EBP is strongly nonequilibrium. It means that the function of the electron energy ...

In this work, we model a radiofrequency discharge of hydrogenated silicon nitride in a capacitive coupled plasma reactor using Maxwellian and non-Maxwellian electron energy distribution function. The purpose is to investigate whether there is a real advantage and a significant contribution using non-Maxwellian electron energy distribution function rather than Maxwellian one for determining the ...
