To remove it, the wafer is submerged in water at room temperature and the edge of the thermal release tape is peeled back slightly, allowing water to seep into and penetrate between the nickel and ...
Top image: Schematics illustrating spin transport in CVD graphene on Si/SiO2 substrate, with ferromagnetic contacts (Co/TiO2) for spin injection and detection. Bottom image: An optical microscope ...
One of the biggest practical issues surrounding graphene is the commonplace methods that require the transfer of graphene onto an intended substrate. Transfer-free graphene is one key area currently ...
