Abstract:
1. A thermoelectric structure comprising: a superlattice film of at least first and second material systems having different lattice constants and interposed in contact with each other; a physical interface at which said at least first and second material systems are joined with a lattice mismatch and at which structural integrity of said first and second material systems is maintained; said superlattice film of at least first and second material systems having a charge carrier transport direction normal to said physical interface and the superlattice film having a thickness of at least approximately 1.35 μm wherein said superlattice film of at least first and second material systems and said physical interface comprise a superlattice structure with the lattice mismatch at said interface occurring in a plane of epitaxial growth of said at least two material systems and providing an acoustic mismatch to reduce thermal conduction across said physical interface; and orthogonally-quantum-confined superlattice phonon-blocking electron-transmitting structures.
