Weak Localization in Graphene: Theory, Simulations, and Experiments

Figure 3

We compare the analytical expression (solid line) for Δ𝑃_ret/𝑃_ret from (17), relevant to the quasi-1D situation, with the numerically obtained relative change in the localization length using the parameter 𝐵_𝑒=100𝐵_𝑐. The different dot colors (blue, red) represent different widths (80×𝑎, 120×𝑎) of the simulated graphene device, where 𝑎 is the lattice constant.
