Deformation splitting of L valleys of the conduction band and intervalley scattering in GaAs
Karlik I. Ya., Katilyus R., Mirlin D. N., Sapega V. F.
A lifting of the degeneracy of the L valleys of the conduction band has been observed in the hot-photoluminescence spectra of uniaxially deformed GaAs crystals. Analysis of the spectra reveals the constant of the intervalley interaction, Dll = (5 + 1) Χ 108 eV/cm, and the constant of the shear strain energy, Έ\ = 15 + 1.5 eV.
