The characteristics of metalorganic chemical vapor deposition (MOCVD) of Bi2Te3, Sb2Te3 and their superlattice structures are discussed in this paper. We have grown c-oriented films on both hexagonal sapphire and fcc GaAs substrates, with specular mo

We report on our investigation into the use of III-V superlattice structures for thermoelectric (TE) applications. Preliminary review of III-V materials trends indicate that the GaSb/InAs superlattice system should offer one of the best potentials fo

We describe a simple, yet phenomenologically very different, low-temperature modification to the conventional metal–organic chemical vapor deposition. It has been applied to the epitaxy of hexagonal-phased Bi2Te3/Sb2Te3 superlattices on zinc-blende

The fabrication of n-type PbTe/PbTe/sub 0.75/Se/sub 0.25/ structures using a simple evaporation technique has yielded high-quality superlattice films, a significant reduction in lattice thermal conductivity and potentially enhanced thermoelectric dev

PbTe-based thin films were deposited by thermal evaporation at temperatures ranging from ambient temperature to 430°C on different vicinal GaAs (100) substrates and BaF2 (111). This materials system is being evaluated as a potential candidate thermo

The Conference Record of the Twenty-Second IEEE Photovoltaic Specialists Conference - 1991.
An approach for inverted-grown AlGaAs/GaAs cascade cells, where the AlGaAs top cell is grown first at high temperatures, placing the surface to be illuminated nearest to the substrate, is presented. Following the growth of the top cell, the GaAs tunn
