Abstract
We investigated, theoretically, the electronic band structures, transport and magneto-transport properties of In0.53Ga0.47As(d1 = 10 nm)/InP(d2 = 5 nm) lattice matched superlattice (SL) at 1.7 K. These studies were performed in the envelope function formalism with effects of well thickness d1. The SL has a direct band gap of 849 meV and the cut-off wavelength of 1.46 μm indicates that it can be used as a short infrared detector. The computed density of states and position of Fermi level, predict that this sample is a quasi two-dimensional system and exhibits n type conductivity. We have interpreted the oscillations in the magneto-resistance observed by Pusep et al. in this superlattice. These results were compared and discussed with the available data in the literature.
