Room temperature energy-efficient spin-orbit torque switching in wafer-scale all-vdW heterostructure
Haiyu Wang, Hao Wu, Yingjie Liu +13
The emergent two-dimensional (2D) ferromagnetic materials with unique magnetic properties have endowed great potential for next-generation spintronic devices with extraordinary mer…
Dimension Engineering of Narrow Bandgap Semiconductor InAs Nanostructures in Wafer-Scale
Dong Pan, Ji-Yin Wang, Wei Zhang +7
Here, we demonstrate an approach that provides a precise control of the dimension of InAs from one-dimensional nanowires to wafer-scale free-standing two-dimensional nanosheets, wh…
Experimental observation of a large ac-spin Hall effect
Dahai Wei, Martin Obstbaum, Christian Back +1
In spinelectronics the spin degree of freedom is used to transmit and store information. Ideally this occurs without net charge currents in order to avoid energy dissipation due to…
Experimental Verification of Comparability between Spin-Orbit and Spin-Diffusion Lengths
Yasuhiro Niimi, Dahai Wei, Hiroshi Idzuchi +3
We experimentally confirmed that the spin-orbit lengths of noble metals obtained from weak anti-localization measurements are comparable to the spin diffusion lengths determined fr…
Giant Spin Hall Effect Induced by Skew Scattering from Bismuth Impurities inside Thin Film CuBi Alloys
Y. Niimi, Y. Kawanishi, D. H. Wei +6
We demonstrate that a giant spin Hall effect (SHE) can be induced by introducing a small amount of Bi impurities in Cu. Our analysis based on a new 3-dimensional finite element tre…
Bi(111) thin film with insulating interior but metallic surfaces
Shunhao Xiao, Dahai Wei, Xiaofeng Jin
The electrical conductance of molecular beam epitaxial Bi on BaF2(111) was measured as a function of both film thickness (4-540 nm) and temperature (5-300 K). Unlike bulk Bi as a p…
Extrinsic Spin Hall Effect Induced by Iridium Impurities in Copper
Y. Niimi, M. Morota, D. H. Wei +5
We study the extrinsic spin Hall effect induced by Ir impurities in Cu by injecting a pure spin current into a CuIr wire from a lateral spin valve structure. While no spin Hall eff…
