From: Spin transport and Hanle effect in silicon nanowires using graphene tunnel barriers
(a) Normal (blue points) and inverted (red points) 3T Hanle data obtained at T=10 K and a bias current of −0.5 μA from a 150-nm diameter Si nanowire with a 7.5-μm wide contact. The solid red line is a fit to the normal 3T Hanle data, and yields a spin lifetime τs=50 ps. A parabolic background has been subtracted. (b) Amplitude of the normal 3T Hanle signal (blue) and corresponding spin lifetime (red) as a function of bias.
