Semiconductor Super Lattices
A superlattice can be formed by alternating thin layers of different semiconductor materials. The result is an artificial semiconductor whose properties differ from those of the constituents. The advantage is that the bandgap energy and the lattice parameter can be varied independently, providing a wide parameter space for bandgap engineering. The presentation will show how the superlattice can grow on available substrates, such as GaSb, and how it functions as a detector of infrared light.
