We have developed an improved 8x8 version of the Transfer Matrix Approach that consider contributions from abrupt interfaces and external fields when tunneling through central barrier exists. We have included the Land\\'e g-factor dependence on the external applied field. Also, we have calculated electron density of states and photoluminescence excitation.
