Gate-tunable spin Hall effect in an all-light-element heterostructure: graphene with copper oxide
Haozhe Yang, Maider Ormaza, Zhendong Chi +10
Graphene is a light material for long-distance spin transport due to its low spin-orbit coupling, which at the same time is the main drawback to exhibit a sizeable spin Hall effect…
Unconventional charge-to-spin conversions in graphene/MoTe2 van der Waals heterostructures
Nerea Ontoso, C. K. Safeer, Franz Herling +9
Spin-charge interconversion (SCI) is a central phenomenon to the development of spintronic devices from materials with strong spin-orbit coupling (SOC). In the case of materials wi…
Spin Hall effect driven by the spin magnetic moment current in Dirac materials
Zhendong Chi, Guanxiong Qu, Yong-Chang Lau +5
The spin Hall effect of a Dirac Hamiltonian system is studied using semiclassical analyses and the Kubo formula. In this system, the spin Hall conductivity is dependent on the defi…
Interface enhanced helicity dependent photocurrent in metal/semimetal bilayers
H. Hirose, M. Kawaguchi, Y. -C. Lau +2
One of the hallmarks of light-spin interaction in solids is the appearance of photocurrent that depends on the light helicity. Recent studies have shown that helicity dependent pho…
Giant inverse Faraday effect in Dirac semimetals
Masashi Kawaguchi, Hana Hirose, Zhendong Chi +3
We have studied helicity dependent photocurrent (HDP) in Bi-based Dirac semimetal thin films. HDP increases with film thickness before it saturates, changes its sign when the major…
The spin Hall effect of Bi-Sb alloys driven by thermally excited Dirac-like electrons
Zhendong Chi, Yong-Chang Lau, Xiandong Xu +3
We have studied the charge to spin conversion in BiSb/CoFeB heterostructures. The spin Hall conductivity (SHC) of the sputter deposited heterostructures exhibits a high…
