Electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb. In addition to the electron, all freely existing charged subatomic particles thus far discove
Instead of adjusting the charges distributed on electrode atoms at each time step to keep the electrode in an equipotential state in GCD-CPM modeling, in GCD-CCM modeling, the charge on each electrode atom is preset with the same value. The electrode potential is computed accordingly, showing ...
Both experimental and theoretical electron densities in ionic basins imply that pressure is a driving force for charge transfer among ions. In theory, with pressures the electronegativity of elements (single atoms) decreases18. In a crystal, two competing processes may be considered. On one hand, ...
presence of diselenide groups in the ZrSe 3 -type layer (invisible by the single-crystal structure analysis) and support the notion that these Se atoms in the [Th 2 Se 6 ] layers accept the extra electron from the alkali metal, and this results in breaking one out of four diselenide ...
Fock's representation of momentum space hydrogenic orbitals in terms of harmonics on the hypersphere S 3 of a four-dimensional space is extended to classif... V Aquilanti,S Cavalli,C Coletti - 《Physical Review Letters》 被引量: 55发表: 1998年 Atomic electron-pair distances and subshell ra...
In certain molecular models, and related one-dimensional field theories, localized objects appear with half-integral expectation values of charge. We consider whether these states are eigenstates of charge, with half-integral eigenvalue. We find that it is indeed so for a suitably diffuse definition...
The critical bias value is given by the expression (where e = the electron charge, N L = layer doping concentration (atoms/cm.<SP>3</SP>), N s = substrate doping concentration (atoms/cm.<SP>3</SP>), d= layer thickness (cm.), # 0 = dielectric constant of free space, # s =...
Since the Berry curvture is the "magnetic" field in reciprocal space, one can guess that with a finite Berry curvature, the real space rx and ry will not commute either: [rx,ry]=iΩz But the commutator between r and k still have the same form: [xi,kj]=iδij . ...
(a ratio present in highly efficient ternary devices28). The energy levels of PCBM mean that both electron and hole transfer from Y6 to PCBM are prohibited. Any reduction in charge recombination rate will therefore be due to interfacial level bending (one would expect the effect of increased ...
This is shown for electron- and hole-only devices of MAPbI3 in Fig. 2. Considering the slow scan rate of 0.46 V s−1, the question arises which value should be taken for the dielectric constant in the SCLC analysis. Another important factor in the analysis is the influence of ...
