Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still ...

The hole current due to recombination in the N epitaxial layer is calculated and compared to the electron current injected into the diffused P region. A formula is given and results are compared with ...

Results of numerical simulation of a miniaturized sub-THz traveling-wave tube amplifier with sheet electron beam and planar grating slow wave structure (SWS) are presented. Cold characteristics of the ...

Teaching the VSEPR (valence shell electron-pair repulsion) model can be a tedious process. Traditionally, Lewis structures are drawn and the number of “electron clouds” (groups) around the central ...

Addition of a series of phenol electron donors to solutions of humic substances (HS) enhanced substantially the initial rates of hydrogen peroxide (H 2 O 2) photoproduction (RH2O2), with enhancement ...
