In article number 2000574, Achim Harzheim, Pascal Gehring, and co‐workers report U‐shaped graphene strips comprising one wide and one narrow leg that form a single material thermocouple due to the increased influence of electron edge scattering in a narrow channel. This leads to different Seebeck coefficients in the two legs, which for the devices tested, yield a maximum sensitivity of Δ S ≈ 39 μV K −1 .
