dc.descriptionDigital Magnetic Heterostructures (DMH) are semiconductor structures with magnetic monolayers. Here we study electronic and magneto-transport properties of shallow modulation-doped (ZnSe/ZnCdSe) DMHs with spin-5/2 Mn impurities. We compare the "reservoir" model, possibly relevant to shallow geometries, to the usual "constant-density" model. Our results are obtained by solving the Kohn-Sham equations within the Local Spin Density Approximation (LSDA). In the presence of a magnetic field, we show that both models exhibit characteristic behaviors for the electronic structure, two-dimensional carrier density, Fermi level and transport properties. Our results illustrate the relevance of exchange and correlation effects in the study shallow heterostructures of the group II-VI.
