Transport Properties of Ferromagnetic Silicene Superlattice-Based Nanostructure

Ferromagnetic Silicene Superlattice Based Thermoelectric Flexible Renewable Energy Generator Device

“…2N ferromagnetic strips interweave (2N-1) normal strips of equally length single-layer silicene [27], [45] are forming the proposed model. This device's source and drain are formed of metal as seen in Fig.…”

“…The transport of valley-spin polarization under induced ac field is implemented. Photon-assisted conduction channels also can be introduced with help of ac-oscillating fields which can be modulated with the gated voltage to set it into the window of conduction of the device [23], [27], [45]- [47]. The transport is distinguishable for spin alignment because of Zeeman splitting which is imposed in presence of magnetic field, there are valley possibilities also in addition to conduction channels of the photo-assisted transport, so this resulted in photon-assisted spin and valley resolved conduction.…”

“…The transport is distinguishable for spin alignment because of Zeeman splitting which is imposed in presence of magnetic field, there are valley possibilities also in addition to conduction channels of the photo-assisted transport, so this resulted in photon-assisted spin and valley resolved conduction. The tunneling probability, ac-field(E) , is calculated as [27], [45]:…”

“…where J n eV ac n ω is first kind Bessel function of order n th , V ac is the induced ac-field peak and ω is its angular frequency and tησ represents transmission coefficient, with η(η ) = +1(−1) conforms to K (K ) valley, σ = +1(−1) is for up spin and down spin configuration [27], [45].…”

“…Hence the calculations will be performed at low temperatures as will be shown in the results below. Then thermoelectric figure of merit, ZT, of this device will be calculated as [27], [45]:…”
