The Mass of the Electron in GaAs/AlGaAs by the Shubnikov-de Haas Effect and Spin-Charge Locking The energy of the free electron gas is calculated in three dimensions. In this calculation an integral over the wave vector space occurs which was solved b... HA Kassim,IA Jalil,N Yusof,......
An electron has been turned into a spiralling wave of mass and charge, with the help of a laser.“Chirality, or handedness, is an interesting and still in part enigmatic feature of our universe,” says Peter Baum at the University of Konstanz in Germany. Chiral objects, like coils or...
A Fermi gas consists of noninteracting electrons, and therefore it is an important starting point for the study of Fermion systems upon switching on interactions. Other metals than the alkali metals do not realize a Fermi gas because of interactions, e.g., hybridization, electron–electron, and...
The results show that the potential barrier of materials can be regulated by changing the contacting metals or dielectrics. It is mainly due to the work function or contact potential difference that have an influence on the propensity or direction of electron transfer between materials. Regulation ...
an electron probe at 80 keV and 30 mrad convergence semiangle. Line profiles of the (g) electrostatic potential and (h) charge density comparing (b,c) experiment with (e,f) simulation. The light blue shaded regions indicate one standard deviation on either side of the mean of the ...
Mass-to-charge ratio The mass of an ion divided by its charge, often given as m/z. The ionized form of the sample molecule, typically formed through addition or loss of an electron or proton. Resolution The ability of the mass analyzer to display two separate peaks for ions of similar ...
Reduction ofelectrostatic chargemay depend on the fibres in terms of charge retention and mechanisms of electron transfer during the generation and dissipation of the charge. Antistatic finishes are applied as an effective antistatic agent on the surface of the fibre and to the surface with which fr...
Recently, an energy window was identified, inside which organic semiconductors are not susceptible to charge trapping. Trap-free bipolar charge transport can be accomplished when the electron affinity (EA) of the organic semiconductor is higher than 3.5 eV and the ionization energy (IE) is lower...
