If we say that all matters are made up of building blocks called elements, elements are themselves made up of building blocks called atoms. Atom is the smallest particle of an element that retains the properties of that element. Atom is composed of nucleu...

Measured band structures of La3Ni2O7 Figure3shows band structures of La3Ni2O7measured along several high-symmetry directions. The observed bands are marked by the guidelines. We took momentum cuts in both the first and second Brillouin zones because, due to the photoemission matrix element effe...
The application of an in-plane field tilts the conduction (CB) and valence band (VB) of the semiconductor (orange lines) and allows the wave functions of the free electrons and holes (gray shaded curves) to leak into the bandgap, which results in an increase of the sub-bandgap absorption...
Neutral and excited atoms densityNeutral and excited molecule densityNitrogen flowing dischargesWe investigated flowing N-2 DC discharges both experimentally and theoretically. The discharge gas and N-2(X-1 sigma(+)(g)) vibrational temperatures, electron density (n(e)), reduced electric field (E/...
electrons (negatively charged particles) around its nucleus. So, if we know the atomic number of an element, we immediately know the number of protons and the number of electrons in the atom of the element. For example, all atoms with the atomic number 6 is carbon ato...
Electrons weakly bound to molecules by dipolar, quadrupolar or polarization forces Within the framework of a simple electrostatic model we here discuss the stability of very weakly bound molecular negative ions. In contrast with the case ... H Abdoul-Carime,C Desfran?Ois - 《European Physical Jou...
According to the electrostatic point of view of the molecule, these electronegative atoms tend to donate electrons. Also, it is found that the most electropositive center charges of [enol, keto, R1(O), R2(O), and R3(O)] and [thiol, thione, R1(S), R2(S), and R3(S)] are ...
(non-impact) mechanisms of defect creation are not realized in wide-gap metal oxides with opposite energetic inequality,EFP>Eg(the value ofEFPis up to 2-3 times higher). Therefore, the elastic collisions of incident energetic particles (neutrons, ions, electrons) with atoms/nuclei of materials...
