Vor 3 Tagen · Because we can inject electrons into the electronic bands of a BNNT layer with 400 nm light pump (3.1 eV) and excluding a two-photon absorption process, there should be a local contact between the ...

Vor 2 Tagen · The unique electronic properties of topological quantum materials, such as protected surface states and exotic quasiparticles, can provide an out-of-plane spin-polarized current needed for ...
Vor einem Tag · In addition to 1- and 2-vinylnaphthalenes, a wide range of styrenes containing an electron-donating or -withdrawing functional group at the para-, meta-, or ortho-position of the aromatic ring ...
Vor 2 Tagen · in which the γ = (γ 1, γ 2, γ 3) and γ 0 are the Dirac gamma matrices related to the spin of the particle. The Dirac equation is true for all spin-1 ⁄ 2 particles, and the solutions to the equation are 4-component spinor fields with two components corresponding to the particle and the other two for the antiparticle.
Vor einem Tag · Most materials in Nature expand when heated, and very limited materials show the opposite behavior, i.e., negative thermal expansion (NTE). Here, we observed that NTE is associated with the rarely occurring Fano antiresonance in Raman spectroscopy and investigated the role of electron–phonon coupling on the negative thermal expansion observed in the multiferroic ErFeO3 perovskite; for this ...
Vor 2 Tagen · The wave function of fermions, including electrons, is antisymmetric, meaning that it changes sign when two electrons are swapped; that is, ψ(r 1, r 2) = −ψ(r 2, r 1), where the variables r 1 and r 2 correspond to the first and second electrons, respectively. Since the absolute value is not changed by a sign swap, this corresponds to equal probabilities.
