AbstractGraphene-based spintronic devices require efficient spin injection, and dielectric tunnel barriers are typically used to facilitate spin injection. However, the direct growth of ultrathin dielectrics on two-dimensional surfaces is challenging and unreliable. Here we report spin injection in graphene lateral spin valves using ferromagnetic van der Waals contacts of indium and cobalt (In–Co), and without the deposition of dielectric tunnel barriers.

3. Results 3.1. Formulation Development for “Jifang E” Sustained-Release InjectionPoloxamer 407 was chosen as a sustained-release excipient because it is a substance with amphiphilic properties of polyethylene oxide (PEO) and polypropylene oxide (PPO), which can be gelled below physiological temperature at concentrations of 15% to 30% (w/v), and the gelling temperature gradually decreases as the concentration increases (Figure 1A).

Abstractvan der Waals heterostructures (vdW-HSs) integrate dissimilar materials to form complex devices. These rely on the manipulation of charges at multiple interfaces. However, at present, submicrometer variations in strain, doping, or electrical breakages may exist undetected within a device, adversely affecting macroscale performance. Here, we use conductive mode and cathodoluminescence scanning electron microscopy (CM-SEM and SEM-CL) to investigate these phenomena.
