Effect of the Dresselhaus spin splitting on the effective Landé g-factor in GaAs–(Ga,Al)As quantum wells under in-plane or growth-direction magnetic fields

Using the non-parabolic and anisotropic Ogg–McCombe effective Hamiltonian, we study the effect of the Dresselhaus spin splitting on the cyclotron effective mass and Landé gg-factor associated to conduction electrons in GaAs–(Ga,Al)As quantum wells under applied magnetic fields, both along the growth- and in-plane directions of the heterostructure. Theoretical results are found in good agreement with available experimental measurements.
