A University of Texas at Dallas physicist has teamed with Texas Instruments Inc. In a general sense, waste heat is everywhere: the heat your car engine generates, for example. A deep dive for these novel measurements, detailed analysis and literature comparisons requires a university group. That heat normally dissipates.
