The size-dependent deformation potentials of CdSe quantum dots are studied by first-principle and semiempirical pseudopotential calculations. We find that the amplitude of the quantum dot deformation potential is only slightly larger than the bulk value, and this increase is mostly caused by the off-Γ point deformation potentials in the bulk, which are larger in amplitude than the Γ point deformation potential.
