With a better understanding of the physics, we can show that the intrinsic spin lifetime is below 1 ns for pristine graphene in its free-standing form. To begin, we consider electron energies, ε = ħv F k, that are much larger than the sub meV energies of flexural phonons (v F = 10 6 m/s is the Fermi velo in graphene). The dispersion of long-wavelength flexural phonons follows ħΩ fp (q ...
