Transport Spectroscopy of Sublattice-Resolved Resonant Scattering in Hydrogen-Doped Bilayer Graphene
Jyoti Katoch, Tiancong Zhu, Denis Kochan +3
We report the experimental observation of sublattice-resolved resonant scattering in bilayer graphene by performing simultaneous cryogenic atomic hydrogen doping and electron trans…
Importance of Paramagnetic Background Subtraction for Determining the Magnetic Moment in Epitaxially Grown Monolayer and Few-Layer van der Waals Magnets
Dante J. O'Hara, Tiancong Zhu, Roland K. Kawakami
Due to the atomically thin nature of monolayer and few-layer van der Waals magnets, the undesired background signal from the substrate can have significant contribution when charac…
Surface Structures of Epitaxial B20 FeGe(-1-1-1) Thin Films via Scanning Tunneling Microscopy
J. P. Corbett, T. Zhu, A. S. Ahmed +5
We grew 20-100 nm thick films of B20 FeGe by molecular beam epitaxy and investigated the surface structures via scanning tunneling microscopy. We observed the atomic resolution of…
Probing Tunneling Spin Injection into Graphene via Bias Dependence
Tiancong Zhu, Simranjeet Singh, Jyoti Katoch +4
The bias dependence of spin injection in graphene lateral spin valves is systematically studied to determine the factors affecting the tunneling spin injection efficiency. Three ty…
Strong and Tunable Spin Lifetime Anisotropy in Dual-Gated Bilayer Graphene
Jinsong Xu, Tiancong Zhu, Yunqiu Kelly Luo +2
We report the discovery of a strong and tunable spin lifetime anisotropy with excellent spin lifetimes up to 7.8 ns in dual-gated bilayer graphene. Remarkably, this realizes the ma…
Topological Dirac Semimetal Na3Bi Films in the Ultrathin Limit via Alternating Layer Molecular Beam Epitaxy
Igor V. Pinchuk, Thaddeus J. Asel, Andrew Franson +6
Ultrathin films of Na3Bi on insulating substrates are desired for opening a bulk band gap and generating the quantum spin Hall effect from a topological Dirac semimetal, though con…
Room Temperature Intrinsic Ferromagnetism in Epitaxial Manganese Selenide Films in the Monolayer Limit
Dante J. O'Hara, Tiancong Zhu, Amanda H. Trout +9
Monolayer van der Waals (vdW) magnets provide an exciting opportunity for exploring two-dimensional (2D) magnetism for scientific and technological advances, but the intrinsic ferr…
Spin inversion in graphene spin valves by gate-tunable magnetic proximity effect at one-dimensional contacts
Jinsong Xu, Simranjeet Singh, Jyoti Katoch +4
Graphene has remarkable opportunities for spintronics due to its high mobility and long spin diffusion length, especially when encapsulated in hexagonal boron nitride (h-BN). Here,…
Modeling the Oblique Spin Precession in Lateral Spin Valves for Accurate Determination of Spin Lifetime Anisotropy: Effect of Finite Contact Resistance and Channel Length
Tiancong Zhu, Roland K Kawakami
The spin lifetime anisotropy is an important quantity for investigating the spin relaxation mechanisms in graphene and in heterostructures of two-dimensional materials. We generali…
