We have been investigating the fabrication and characterization of superlattices of amorphous materials Se and As2Se3 fabricated using rotational evaporation. The multi-nanolayer structure produced from this fabrication method has been confirmed using TOF-SIMS. We used UPS, DLTS, spectroscopic ellipsometry and I-V measurements to study the energy band structure, optical characteristics and transport characteristics of the superlattice structure. From these measurements, we observed typical superlattice features such as oscillation in the IV characteristics with regions of negative differential resistance.
