Low-resistance spin injection into silicon using graphene tunnel barriers.
Spin manipulation in a semiconductor offers a new paradigm for device operation beyond Moore's law. Ferromagnetic metals are ideal contacts for spin injection and detection, but the intervening tunnel barrier required to accommodate the large difference in conductivity introduces defects, trapped charge and material interdiffusion, which severely compromise performance. Here, we show that singl...
متن کاملDeconvoluted Si 2p Photoelectron Spectra of Ultra thin SiO2 film with FitXPS method
The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...
متن کاملTunnel barrier fabrication on Si and its impact on a spin transistor
The realization of many future spintronic devices requires efficient spin injection into semiconductor structures. Critical considerations include interfacial intermixing of the metallic components and oxygen with Si, and the conditions for Schottky barrier formation. Both impact the design of a silicon-based spin transistor, which tunnelinjects carriers from a ferromagnetic emitter into the Si...
متن کاملAtomic-Scale Engineering of Abrupt Interface for Direct Spin Contact of Ferromagnetic Semiconductor with Silicon
Control and manipulation of the spin of conduction electrons in industrial semiconductors such as silicon are suggested as an operating principle for a new generation of spintronic devices. Coherent injection of spin-polarized carriers into Si is a key to this novel technology. It is contingent on our ability to engineer flawless interfaces of Si with a spin injector to prevent spin-flip scatte...
متن کاملترابرد الکتریکی وابسته به اسپین در ساختارهای نامتجانس Fe-MgO-Fe
In this paper, spin-dependent electrical transport properties are investigated in a single-crystal magnetic tunnel junction (MTJ) which consists of two ferromagnetic Fe electrodes separated by an MgO insulating barrier. These properties contain electric current, spin polarization and tunnel magnetoresistance (TMR). For this purpose, spin-dependent Hamiltonian is described for Δ1 and Δ5 bands in...
