We studied some GaInAs-AlGaInAs semiconductor superlattices grown by molecular beam epitaxy and lattice matched to InP substrates. We performed photocurrent and photocurrent-voltage under monochromatic illumination at different energies measurements. The spectra recorded at \(80 \mathrm{~K}\) exhibi

We have investigated the energy spectrum of a superlattice with wide quantum wells under the bias of an electric field perpendicular to the superlattice layers. By using photocurrent spectroscopy, transitions of Wannier-Stark levels for the various electron and hole states are observed, and at low f
