Electronic structure of rare earth arsenide/gallium arsenide superlattices

Electronic Structure of Hetero-Crystalline Superlattices

In the present thesis we implement a simple numerical method to solve a onedimensional time-independent Schrödinger equation in any arbitrary periodic potential. We apply this method to study the energy band structure, the Bloch wavefunctions and the 1D-density of states of a simple 1D-superlattice model. The results obtained for this model exhibit nontrivial features of real hetero-crystalline...

Electronic structure of intentionally disordered AlAs/GaAs superlattices.

We use realistic pseudopotentials and a plane-wave basis to study the electronic structure of non-periodic, three-dimensional, 2000-atom (AlAs)n/(GaAs)m (001) superlattices, where the individual layer thicknesses n,m ∈ {1, 2, 3} are randomly selected. We find that while the band gap of the equivalent (n = m = 2) ordered superlattice is indirect, random fluctuations in layer thicknesses lead to ...
