Venkatasubramanian, R., Siivola, E., Colpitts, T., & O'Quinn, B. (2008). Phonon-blocking, electron-transmitting low-dimensional structures. (U.S. Patent No. 7342169). http://patft.uspto.gov/netacgi/nph-Parser?patentnumber=7342169

Abstract

A thermoelectric structure and device including at least first and second material systems having different lattice constants and interposed in contact with each other, and a physical interface at which the at least first and second material systems are joined with a lattice mismatch and at which structural integrity of the first and second material systems is substantially maintained. The at least first and second material systems have a charge carrier transport direction normal to the physical interface and preferably periodically arranged in a superlattice structure.
