|+||<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).|
