 +<​DeformationPotential Unit="​eV">​-7.2</​DeformationPotential>​ corresponds to "​a_c"​ of Vurgaftman (i.e. for the conduction band only) in the isotropic approximation. It is used to calculate the shift of the conduction abnd edge due to strain.
 +It is also used to calculate scattering by acoustic phonons (which is a very small effect, almost negligible in typical QCLs).
