Phonon-blocking, electron-transmitting low-dimensional structures
A thermoelectric structure and device including at least firstand second material systems having different lattice constants andinterposed in contact with each other, and a physical interface atwhich the at least first and second material systems are joinedwith a lattice mismatch and at which structural integrity of thefirst and second material systems is substantially maintained. Theat least first and second material systems have a charge carriertransport direction normal to the physical interface and preferablyperiodically arranged in a superlattice structure.
