Within a new perspective which includes the consideration of spin-up and spin-down electrons, a quantum-box approach is used to find a closed mathematical expression for the quantized electrical conductance of an imperfect point–metal contact. From this expression, both proper and improper fractions...
When the current flows a ferromagnetic metal, the supply of both spin-up and spin-down electrons in the semiconductor is overwhelmingly high. Both states with spin-up and spin-down are equally populated, and the current running through the semiconductor remains unpolarized. To overcome this spin ...
The spin Hall effect (SHE), which is responsible for SOT, generates a transverse spin current that is induced by the numerical imbalance of deflected spin-up and spin-down electrons in a heavy metal owing to strong spin-orbit coupling13. The spin current is absorbed by an adjacent ...
An infrared pulse (blue) excites the electron dynamics in bulk Na3Bi. Due to strong spin-orbit coupling, the ‘spin-up’ electrons (red arrow) and ‘spin-down’ electrons (blue arrow) follow different motion, which can be tracked by the emitted harmonic light (blue ...
• spin-up or spin-down• or For example, in the diagram below helium is in its electron ground state. One of its electrons is spin-up, the other is spin-down. Alternatively, one of its electrons has positive spin, the other has negative spin....
Both readout methods are equivalent and give rise to a current ‘blip’ through the SET which is used to discriminate between spin-up and -down electrons. The average readout fidelity of spin-up and -down are estimated to be 96.2 ± 1.1% and 97.6 ± 2.1% for qubit-L and...
The junction filters spin-up (minority spin) electrons while allows spin-down (majority spin) electrons to pass with a filtering efficiency of about 99.5% at low biases. The spin-down electrons are found to tunnels through the junction via the HOMO orbital of the Mn-phthalocyanine molecule. ...
Orbital orbital is the orbital index. This integer must satisfy '0 <= orbital < Int32.ManValue'. Spin spin is the spin index. For electrons, spin=0 is spin up, and spin=1 is spin down. This integer must satisfy '0 <= orbital < Int16.MaxValue'.Methods...
Because of the form of the exchange-correlation hole (see above), electrons of the same spin can avoid one another more efficiently than electrons of opposite spin. This leads to different electron distributions for the spin-up (α), and spin-down (β) electrons. View chapter Reference work...
