Webb23 mars 2024 · Device miniaturization and low-energy dissipation are two urgent requirements in future spintronics devices. The narrowest zigzag graphene nanoribbons (ZGNRs), which are composed of just two coupled carbon-atom chains connected with carbon tetragons, are promising candidates that meet both of the above requirements …

Webbför 2 dagar sedan · In non-spin-degenerate TE materials, spin provides a new dimension for the enhancement of the S. (32) There are four main ways of spin caloritronic effects that have been applied to enhance the S: (33) magnon drag, paramagnon drag, spin entropy and spin fluctuation (SF). The spin Seebeck effect (SSE) provides a new dimension toward S … Webb9 juli 2013 · Abstract We theoretically investigate the longitudinal spin Seebeck effect, in which the spin current is injected from a ferromagnet into an attached nonmagnetic metal in a direction parallel to the temperature gradient. oral-b 1000 battery replacement
