An epitaxial nanocomposite approach is developed for exploring spatial control of oxygen vacancy-driven topotactic phase transition of La 0.7 Sr 0.3 MnO 3-x (LSMO).. The ultrahigh density of epitaxial interfaces created in the self-assembled LSMO-NiO nanocomposite films strongly influence the oxygen vacancy formation and topotactic phase distribution in LSMO.

Cyclophane with eclipsed pyrene units enables construction of spin.

Towards this goal, an integrated spin–photon interface would be a major leap forward as it combines the memory capability of a single spin with the efficient transfer of information by photons.

Low-Temperature Atomic Layer Deposition of Hafnium Oxide for Gating.

(a) Scheme of asymmetric van der Waals metal-semiconductor-metal diode based on two-dimensional Janus MoSSe (scattering region) and 1T MoS 2 (drain and source electrodes). The red squares indicate different contact interfaces with disparate Schottky barrier heights and band bending directions (S-S contact at source side with an n-type barrier and S-Se contact at drain side with a p-type.

Here, we report the observation of spin injection and tunable spin signal in fully encapsulated graphene, enabled by van der Waals heterostructures with one-dimensional (1D) contacts. This architecture prevents significant doping from the contacts, enabling high-quality graphene channels, currently with mobilities up to 130 000 cm 2 V –1 s. Scientific Publications.

The efficiency of spin current generation is paramount. Equally important is the efficient transfer of this spin current across the ferromagnet/heavy metal interface. Here, we show theoretically and experimentally that for Ta as heavy metal the interface only partially transmits the spin current while this effect is absent when Pt is used as.

Spintronics: How an atom-thin insulator helps transport spins.

Giant negative magnetoresistance driven by spin-orbit coupling at the LaAlO 3 /SrTiO 3 interface Physical Review Letters 115, 016803 (2015) arXiv:1412.5614. 22) S. Goswami, E. Mulazimoglu, L.M.K. Vandersypen and A.D. Caviglia Nanoscale Electrostatic Control of Oxide Interfaces Nano Letters 15, 2627(2015) arXiv:1410.2237. Current-generated spin arising from spin-momentum locking in topological insulator (TI) surface states has been shown to switch the magnetization of an adjacent ferromagnet (FM) via spin-orbit torque (SOT) with a much higher efficiency than heavy metals. However, in such FM/TI heterostructures, most of the current is shunted through the FM metal due to its lower resistance, and recent.

Here, the nano-bio interface refers to the physical interface between the cell membrane and nanoscale surface topography. We use nanofabrication to precisely. The in-plane electric current in the Pt film comprises more than 90% of the total current flowing through the bilayer, owing to the lower Pt resistivity. This electric current creates a pure spin.

We present a novel low-temperature (30 °C) atomic layer deposition process for hafnium oxide and apply the layers as gate dielectric to fabricate devices out of the thermally sensitive topological insulator HgTe. The key to achieving self-limiting growth at these low temperatures is the incorporation of sufficiently long purge times ( ≥150 s) in the deposition cycles. We investigate the. Spin spirals (SS) are a special case of noncollinear magnetism, where the magnetic-moment direction rotates along an axis. They have generated interest for novel phenomena, spintronics applications, and their potential formation in monolayers, but the search for monolayers exhibiting SS has not been particularly fruitful.

Spin-polarized neutron reflectivity (PNR) was utilized to study the interface magnetism at the heterostructure of Bi 2 Se 3 /EuS (Fig. 2 c) [ 32 ]. The PNR result shows that the Bi 2 Se 3 /EuS bilayer has a ferromagnetic order at the interface, and this topologically enhanced interfacial ferromagnetism can persist up to room temperature (Fig. 2 d).
