a DFT-computed 3D Fermi Surface of WP2. b Top view of the Fermi surface. Arrows illustrate wave-vectors during an inter-band Umklapp and small-angle scattering event. \(\vec k_{i,n}\) and \(\vec k_{f,n}\) are carrier momenta, \(\vec k_{f,2} - \vec k_{i,2} = \vec q\) and \(\vec k_{f,1} - \vec k_{i,1} = \vec G + \vec q\)
