The electron band structure in a three-dimensional regimented quantum dot superlattice is analyzed using an envelope function approximation. It is shown that the electron density of states effective mass and carrier mobility in these structures are drastically different from those in quantum well superlattices and bulk materials. By changing the size of quantum dots, inter-dot distances barrier height and regimentation one can effectively tune the electronic properties of the quantum dot superlattices and make them suitable for a variety of device applications.
