                      devices that yields enhanced spin and charge transport
                      properties by improving both the electrode-to-graphene and
                      graphene-to-substrate interface. First, we prepare Co/MgO
                      spin injection electrodes onto Si++/SiO2. Thereafter, we
                      mechanically transfer a graphene–hBN heterostructure onto
                      the prepatterned electrodes. We show that room temperature
                      spin transport in single-, bi-, and trilayer graphene
                      devices exhibit nanosecond spin lifetimes with spin
                      diffusion lengths reaching 10 μm combined with carrier
