Spin-Flip Noise in a Multi-Terminal Spin-Valve [PDF]

open access: yes, 2003
We study shot noise and cross correlations in a four terminal spin-valve geometry using a Boltzmann-Langevin approach. The Fano factor (shot noise to current ratio) depends on the magnetic configuration of the leads and the spin-flip processes in the ...

Optimal selection of inner-branches parameters of matching circuits under the minimum branch-current RMS values and zero active-power conditions [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
The article is a continuation of a study on the synthesis of matching multi-terminal networks, also known as compensators. The reactive four-terminal-network compensators for linear loads were introduced in previous publications, but it appeared that ...

MAPbI3-on-CuInSe2 two-terminal monolithically integrated and four-terminal mechanically stacked tandem solar cells: A Theoretical Investigation Using SCAPS-1D

open access: yesResults in Optics, 2023
Two-terminal (2-T) and four-terminal (4-T) tandem solar cells with wide bandgap perovskite (MAPbI3) as the top sub-cell and low bandgap copper indium diselenide (CuInSe2, CIS) as the bottom sub-cell have potential to outperform the single-junction power ...

Four‐Terminal Perovskite/Silicon Multijunction Solar Modules

open access: yesAdvanced Energy Materials, 2017
Multijunction solar cells employing perovskite and crystalline‐silicon (c‐Si) light absorbers bear the exciting potential to surpass the efficiency limit of market‐leading single‐junction c‐Si solar cells. However, scaling up this technology and maintaining high efficiency over large areas are challenging as evidenced by the small‐area perovskite/c‐Si ...
