We examine the validity of the spherical approximation γ s = ( 2 γ 2 + 3 γ 3 ) / 5 in the Luttinger–Kohn Hamiltonian in calculating the subband dispersions of the hole gas. We calculate the realistic hole subband dispersions (without the spherical approximation) in a cylindrical Ge nanowire by using...
