When expressed in atomic units, the elementary charge takes the value of unity; i.e., e = 1. Thus, the electron’s charge can be denoted by -e. Although the proton is much more massive than the electron, it only has a charge of e. Hence, neutral atoms always bear the same number...
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
Electron correlations often lead to emergent orders in quantum materials, and one example is the kagome lattice materials where topological states exist in the presence of strong correlations between electrons. This arises from the features of the electronic band structure that are associated with the...
electron Fermi surfaceFermi arcpseudogapcuprate superconductorsThe recently discovered charge order is an intrinsic and universal property of cuprate superconductors, however, its microscopic origin remains debated. Here we review briefly the theoretical work about the nature of charge order in cuprate ...
A free neutron—one that is not incorporated into a nucleus—is subject toradioactive decayof a type calledbeta decay. It breaks down into a proton, an electron, and an antineutrino (theantimattercounterpart of theneutrino, a particle with no charge and little or no mass); thehalf-lifefor...
recently discovered three-dimensional plasmons in electron-doped cuprates6,7. The large range of models proposed to describe various aspects of the cuprates reveal the need for evermore detailed measurements of the electron correlations that can be used to narrow down the Hamiltonian parameter space...
Nanoscale self-organization of electrons is ubiquitously observed in correlated electron systems such as complex oxides of transition metals. The phenomenon of charge ordering (CO) or the formation of charge stripes, as observed for layered-structure cuprates and nickelates, is one such example. Amo...
By means of some bold but simple hypotheses he appears to obtain a model of an electron (or proton) which is capable of holding its parts together against the electric forces of repulsion between these parts.DOI: 10.1038/189995a0 被引量: 23 ...
Photoinduced CDW state with topological defects in this material has been discovered from ultrafast electron diffraction and related studies7,28. The non-centrosymmetry in LaTe3 was established from the structure determined by single crystal x-ray crystallography33 as well as from the appearance of ...
Moreover, the positive charges are discovered near the interface between HfO2 and SiO2 films, which may have an impact on the performance of the charge- trapping memory but were neglected in previous models and theory. 1 Beijing National Laboratory of Condensed Matter Physics, Institute of ...
