    • Although our measurement is at the (Equation presented) point, we expect (Equation presented). The acoustic deformation potential can be written as the area ((Equation presented)) derivative of the electronic band energies as, (Equation presented) [41]. Even though the concept of acoustic deformation potentials is usually restricted to band extrema, it is instructive to evaluate (Equation presented). We find that, on the (Equation presented) line, (Equation presented) exhibits only a relatively moderate variation between (Equation presented) and (Equation presented).
