We have studied transmission of holes by a multiband-multichannel model. We combined the effective Hamiltonians of the k-p approach with the multichannel transfer matrix approach. We have shown that using an orthonormal basis derived from quadratic eigen value problem, the important flux conservation requirement was rigorously satisfied. For calculation of transport properties of multichannel-multilayered systems, we employed the finite periodic systems theory. The transmission amplitudes matix, which like the scattering matix contains entire information on the scattering process described by the model Hamiltonian. By obtaining transmission amplitudes one can easily determine transmission coefficients, and specific transport properties such as the channel interference characteristics and global quantities such as the Landauer conductance as function of the incoming Fermi energy and the heterostructure parameters. We studied all amplitudes of heavy and light holes at the same time. This study has benefit of identifying inter and intra-band hole transitions.
